Nah, it's double elimination, so everyone who loses in the upper bracket gets sent to the lower bracket, so that the winner of the lower bracket gets to play the winner of the upper one in the end.

However, most people don't seem to like being branded as those in the "loser" bracket, and for some reason instantly forfeit when they lose in the upper bracket. So far Quickz and myself were the only ones who deigned themselves to actually play a game in the lower one. ;-P
