Throw from F2 hits batter's bat on backswing - Call?

[josephrt1]

Challenging question:

1. In USA/ASA softball, if no play is being made and there is accidental contact with the catcher's throw and the bat, the ball is dead and runners can not advance. (7.6.U) No penalty to the batter.

Then it gets hard!

1. Since batter is still in box in the video they do not violate 7.6.R (hindering while out of box)
2. If the batter is in the box and "actively hinders" (7.6.S) the catcher, batter is out. Since in the video the batter was swinging, this is "actively hindering". But not sure i call this batter out. They were in the box finishing a natural swing. How do you call someone out for this situation.
