The acceleration of racquet from prior to impact, impact, and post-impact, have all one common denominator. It is the point of rotation which is his wrist, like a door hinge.

If he starts on SW grip, the stringbed angle to impact will be too close, which the ball will always hit the net.
How like a door hinge? Forearm pronation or wrist flexing?
