Now I can see what you are talking about. When you draw the rest comes the whole way back and the string will be only the length it needs to be to get your rest the whole way up. The QAD stops when it hits the right spot.
Does the rest you have do that? Or, can you keep raising the forks? If you would serve it in so that the string is either facing to the right or right and back the loop will rest off to the right instead of the left.
Here is a picture of how mine is tied in.
I draw the bow back and then let down and thestring will stay in place due to the pressure from the cable. Then I serve below.
