There, we should be in 100% disagreement now!
There is definitely conscious action, it is not like Nadal showed up and was swinging his hand loosely for the heck of it. But the major part of the motion is due to maintaining the arc. It is not a matter of pulling the racket to the right. That is not the apt way to describe what is going on. Just like the idea of pulling across has been completely debunked. It would look like that video mentioned earlier with the person almost losing balance.
