I think you are splitting hairs. But definetly not a jerk imo (who wants to play jerky?).
But a acceleration of the racket, mainly by bending the elbow, pulling it inwards/upwards depending on which way the elbow points is what I am talking about.
I guess the main discussion here is whether this happens only because of the natural kinetic chain, or also sometimes because of applying of force. I think the acceleration and applying of force through bending of the elbow (in a controlled, not jerky way) is usefull, and is seen in the Federer video.
