@toquoctrian I dont really catch ur idea, but i think he did it so to control the balance, i mean that serve was the strong flat serve according to his motion. So his knees (right and left also) needed to pulled up more (actually faster) than a second kick serve to substract with the momentum of his right hand. He would control his balance better. This serve could be more powerful than other flat serves of Fed :D.
Thanks for the info. This is my idea. Federer is the only player I see doing this. Why other players do not do it?

Can anyone explain why his left knee here is bent and pulled up towards his chest as he strikes the ball more than some other videos?
