I don't see the difference. Based off the edit he very well could've just caught the ball and brought it back down before shooting it.
Yes, that is the point being made. His shooting motion has become consistently 1 smooth motion which improved his efficiency from 3.
THe point is that there's not a difference between the two shots? You sure? Then why are they asking for the difference? I think it's the other way around and based off that edit there's no way of telling. It's intentionally deceiving.
