By the way, I believe "The ball shall be out of bounds when any part of the ball passes over the backboard from any direction." is not well defined.

Yes, that rule seems to contradict the other rules and generally makes no sense. What if you shoot a high arcing shot from just inbounds at the endline (not necessarily directly behind the backboard, maybe off to one side), such that part or all of the ball passes over the top of the backboard from behind (without touching a support) and it lands in the basket. Is the ball ruled to have gone out of bounds as it passed over? That's sometimes used as a trick shot in HORSE. I've actually had people tell me that shot is illegal because the ball is considered out of bounds.

Didn't Larry Bird do this in an NBA game years ago?  He was behind the backboard, near the edge, and arced a shot over the backboard for a score.  Then the rules were changed.
