That is the difference between the hitting chip and the hitting pitch. During the chip and pitch you will use #1 as the engine of the stroke. For the pitch add some #2 and swing the forearms parallel to the ground (stage two) and you will have the hitting pitch. The hitting motion already has an angled hinge built into it so you should be in business.
In summary the difference in the two is the # of accumulators being used and the distance you swing your arms.
