They made EVM themselves or with help from outside. They designed it that way if someone presses a sequence after voting, all the next votes goes to a particular candidate. In short, they input the sequence they made to prove their point. Pretty sure no matter how exact they tried to make their EVM to look similar to the official EVM, most likely the working inside is totally different, unless they got hands on the schematics of original EVMs. Either they have hit the bull's eye or scored a big zero lol. EC denied them access to the original EVMs if I am not mistaken.
