Luke Skywalker: Why not use auto-pass for fisher-timed games?

I mean I guess I always try to play for win/loss, and not timeout of my opponent - so if an auto-pass can help keep a game going even if it's fisher-timed game, I can only see that as a disadvantage to those who try to wait until their opponent is off-line to play their move in the hopes to get them to time out.... which I guess is one way of doing things but what is the point of playing games if you are not going to let your opponent move? OK, sorry... i'm getting off on a tangent.... I try to not even play fisher-timed games anyway...
