The difference with land based versus water based movements is that when you jump you throw your arms up while your feet are still pressing on the SOLID ground. If you swung your arms up after you feet left the ground the would reduce the height of your jump. Unless you launch your arm by pressing against the water you are essentially doing the recovery in the air and as your muscles throw the arm forward an equal and opposite force is pulling backward on your shoulder and body, so you slow down when you start the recovery and then speed up at the end as the momentum in your arm pulls your shoulder forward. In any case, the magnitude of the forces involved in your arm momentum are going to be relatively small in relation to the forces in your pull, I would concentrate your efforts there. I also bought a GoSwim video with Roland Schoeman, and one of the things he does is throw the shoulder. I agree that it wouldn't be the main source of momentum, but would it not be like swinging your arms forward while jumping? I think most of us can jump higher and farther with an arm swing than without. In the case of jumping, the legs are the main propulsive element but the arms do contribute propulsive work. In swimming, the catch arm is the the main propulsive element, but similarly I would think the right arm could do the same. A little experiment to try; stand up straight but don't try to dig your feet into the ground. Then do an forward overarm swing, and watch how you lean forward. Again, I'm not in any way advocating a strong throw or anything. But I think a little velocity or swing on the recovery will add to propulsion. Now if the timing is all off the energy could be completely lost.
