WHAT??? No it doesn't. How does it make sense, that after the throwing motion is completed, but the ball not thrown, then (again, after the attempted throwing motion is complete) he fumbles, and it ruled an incomplete pass.
Guess what, 99.999% of the time the QB "drops back to pass" he plans on throwing it, but doesnt always get to. He wanted to throw it, decided not to, then, later, he fumbled. How come every QB fumble doesn't fit under that rules juristiction, because unless its a QB draw, they were planning on throwing a pass, and thus whether the ball is moving backwards, forwards, or back in time it could potentially be ruled a "tuck"
