I still don't get the point. If the ball is moving toward the racket at an angle, and the racket is moving forward towards the intended target area, the ball will not be reflected according to the laws of reflection, but will be reflected much less. Otherwise, you could never return a cross court topspin back crosscourt.

Conservation of momentum does not even apply here, because there is a net force being imparted to the racket.
