Another thing is that when you slow down your opponent will likely slow down too, and if he doesnt he is at least getting the same amount of extra time to think about the hand. When both players play fast, noone is at a disadvantage, and a tacit agreement is kind of reached.

Also, if you think you have an edge and can play fast relatively at least as well as you opponent (which both players think in a very large percentage of high stakes hu matches), then you want to play as fast as possible to get as many hands in as possible.
