Now im no expert, that hardly shocked anyone , this IMPACT thing has me , i always said its about lining the club up behind the ball aiming where you want it to go then geting the club back to this exact set up position .. so for me its always about the position / relationship of the ball and the club at IMPACT .. how you get the club away from and back to the moment of impact is not as important ..

Setup and Impact positions are significantly different.
Your Pro may well have been given the impression that they are the same! Or he may well have glossed over the difference because he figured you didn't need to know.
There are plenty of myths about the golf swing that have been knocked down and plenty more to go! Whether the elimination of such myths really matters is a different question though!
