As long as
@SliceGirl didn't touch the ball before it bounced the 2nd time: until the ball lands for the 2nd time or hits a fixed object, the play is still "live" and touching the ball would be a loss of point.
For the same reason, if I hit a winner but touch the net before the point is over, no matter whether my opponent was even in the right zip code, I lose the point. Djokovic did this vs Nadal in a GS final.
