This is correct but with the nuance introduced by user jauk: if Azarbaijan seizes Armenian territory bordering Iran, then Iran will have to intervene.
Of course, even then support to Armenian forces would be preferable over direct military action. However as you highlighted the current western- and zionist-friendly administration in Yerevan is a defeatist one that is not interested in confronting Baku (perhaps this treasonous passivity is part of an assignment it received from Washington and Tel Aviv).
This leads me to elaborate on my previous explanations as to how Iran could proceed (point 1) of my post in question - short- to mid-term solutions). Iran should lend support to the Armenian opposition, and do so with plausible deniability. If there is a serious move to topple Pashinyan and replace him with a more patriotic, less NATO-subservient figure, Iran ought to back it.
Secondly, if Azarbaijan really dares to occupy Zangezur and if the present administration in Yerevan stays in power, Iran could set up a non-state Armenian resistance movement. Armenians, including in the diaspora, have a history of non-state militantism, as exemplified by the ASALA group (Armenian Secret Army for the Liberation of Armenia). And there's no lack of Armenians fed up with the current government's defeatism.
The resistance formation Iran could help to build would not engage in terrorism but fight a regular guerilla war against Baku regime forces in a hypothetically occupied Zangezur. Complete with the best weaponry, intelligence, logistics and training Iran may offer. As well as a perfect safe haven on Iranian soil to retreat to after hit and run attacks.
Thirdly, Iran should not miss the opportunity to inform the Armenian public about the deep zionist involvement in propping up and arming the Baku regime, and insist on this aspect above all. While also underscoring Pashinyan's zionist-friendly leanings, and asking what good it did to allow a zionist "embassy" in Yerevan, since Tel Aviv hasn't stopped throwing its weight behind Baku's expansionist policy to the detriment of Armenia. The Armenian opposition ought to be encouraged to adopt this line of discourse.
This is actually not to be taken lightly.
What is an Iranian national symbol doing on the "flag" devised by Azarbaijan Republic nationalists for the Zangezur corridor they dream of occupying?
Read between the lines: this is a signal to the exiled anti-IR opposition, namely monarchists and MKO, and part of a broad policy to enlist their support for Baku's endeavour, which ultimately aims at separating Azari-speaking regions from Iran herself.
The fingerprints of the zionist regime and NATO are all over this, as it's them who are actively sponsoring every single one of Iran's enemies, and have been actively working to connect these assorted enemies and oppositionists with each other, and make them coordinate their actions.
By the way, as you can see Baku regime forces have not quite taken the border zone with Iran, so the Islamic Republic did well to hold back so far. Hopefully this may serve as an inspiration not to judge all too quickly, and to be confident in the Iranian Leadership's wisdom and competence.
Tel Aviv is the driving force and mastermind behind anti-Iranian Azari separatism. Isra"el" is also the main source of cutting edge weaponry for the so-called Republic of Azarbaijan. The threat emanating from Baku can't therefore be fully appreciated without taking into account the zionist factor.

But the zionist regime does not restrict itself to supporting Azari separatism against Iran. It is also involved with Kurdish separatists, Arab separatists eyeing Khuzestan and others.
Moreover, zionist- and western-sponsored media are the forefront of a very extensive campaign to make the "ethnic" disintegration of Iran theacceptable to Iranian people themselves, by promoting the notion of an "ethnicity"-based federalization of the Iranian polity.
These same western and zionist powers have also directed the exiled anti-IR opposition they bankroll (shahis, MKO, secular nationalists, liberal democrats, leftists etc) to endorse this extremely dangerous agenda. Hence Reza Pahlavi's regular meetings with separatists oppositionists and so on.
Tel Aviv and NATO remain in pole position of the existential threats Iran is facing, since they are the ones pulling the strings of hostile client states in Iran's vicinity as well as of separatist opposition and terrorist grouplets.
