The racket tip still continues to move further away as you pull. You're bending at the elbow and pulling the arm back, not the racket tip.The racket tip continues to move further away from the body after contact, then starts coming towards the body again. So there is not pulling back around contact or just after it. The coming across is just the completion of the swing. By the time the racket tip's distance from the body starts reducing, the ball is long gone.
