Picking up the load later is definitely the goal, but like anything, it can not be addressed in isolation. It is the result, not the action. You are right, it is a result of your path off the second wake, which is a result of the speed at your gate. Maintaining static pressure into the wakes, or close to it, allows you to leave the wakes without losing your structural alignment or your direction. This sets up a faster (not sharper) turn allowing your speed to decrease at a slower rate. The longer you can maintain speed through the turn, the later, and just as importantly the lighter the load on the rope will occur.
Its all connected.
