The Orlando Magic announcers actually explained it pretty well. It’s not the hanging when Paolo is running by him - it’s when his legs come down, what they are expecting you to do is come back down and kinda hop down like you’re coming off a swing. What Tatum does it pump up with his knees to his chest before releasing. THAT is the action that could damage the rim and that little flourish will get you called every time.

I don’t agree totally, but it was interesting to see what the ref called vs what the announcers said vs what everyone on reddit is commenting on.
