I think it's just as likely that he hoped the ref would make the call, which is why he gave her time to do so. I don't have a problem with how Yapp reacted here. He should not be expected to referee the match when someone is there to do so. No other athlete, in any other refereed sport is expected to penalize themselves.
People in general are basically dishonest given the chance. I would not expect them to call a penalty on themselves. Camaras everywhere now though have put a little fear into people. Not that it has changed their instincts, they are just a little more fearful of consequences.

What is the defensive play in golf? No matter what, in golf you get credit for your performance. Your opponent has no effect. In boxing, tennis and pool, your opponent can beat your brains out.
