They both have the same movements, they're just randomly mashing the d-pad and face buttons. Same shit you've seen hundreds of times both animated and in live action when someone wants to act that they are playing a game, usually by an actor, director, or animator is a non-gamer. The times it doesn't happen are so uncommon that it tends to be notable.

Not to mention that they are both playing Doom, which AFAIK only the PC version back then had any sort of multiplayer (and that was over two PCs).
