Test for yourself. take your racket and internally rotate the arm with the wrist laid back and then with the wrist and racket being in line. only in one case the racket will close.

also why is feds racket face opening in the video at 3:00 when his arm is internally rotating?

Internal rotation of the arm is very important because in greatly contributes to RHS but it doesn't close the racket face.
