Two rules questions inspired by NFHS test

[Manny A]

Almost every rule set in both softball and baseball treat a batted ball that hits the top of the fence and then continues over the fence as a home run. The theory is that the ball had already passed the front plane of the fence/wall in flight, so once it hits the tubing and angles away from the field, it has already gone beyond that front plane in flight.

But if the ball bounces of the tubing and goes back toward the field, then the ball hasn't completely passed the front plane, and is no longer in flight. So if it subsequently contacts the fielder and then goes over, it is treated as a "ground" ball that deflects off the fielder for a two-base award.
