Maybe I'm missing something, but I think not: the first point of it is that it will never happen that the match is even, someone will always be leading. So it affects even the very first game, unlike in the current set up, where the first game (Trompowsky?!) is not a real game. At the beginning of the first game, someone would already have to play like they are behind. It also means that a you (I think) don't get situations where a draw is "good enough", a draw always solidifies someone's lead. That said there might be other consequences that I don't see.
