I think it's possible that he wasn't cheating. Some people don't realize how late they get to the ball and they think they get it just before it hits the ground as opposed to just after. It's also the angle that you view it at, people are stretching and they aren't looking at the ball at contact (that's why there are so may "tips" telling you to watch the ball through contact. I would definitely say that it bounced twice, but it's ultimately his call. If it were me, and you said it bounced twice I'd probably take your word for it as you are in a better position to see it than me. Though I do know it's my call.
