That doesn't make any sense. I can get my elbow out front in the same way using pendulum physics in the shoulder as I can simply exerting muscle to pull the elbow out. The difference is that there is more energy in the system if you use all of the forces available. If what you are saying is true, everyone would be able to throw max D with Beato drills. This isn't the case, so there must be a reason why. Your understanding is that the large muscles are loaded up when the elbow is out front, but if you simply place your elbow in such a position the muscles are in fact not loaded up. Why? Because there is less energy in the system.
You said earlier that the shoulder was to just get the disc moving in the right direction. In that statement you are agreeing with me. The entire system, including the disc, has a moment of inertia. The moment of inertia is the required force to start movement. When you "get the disc going in the right direction", you have in fact exerted force to overcome the moment of inertia which would be dragging your system down without the shoulder part of the system. When you throw with a Beato drill, you have to overcome the moment of inertia and that takes up some of the energy of the system as a whole.
You also stated that you have to actively pull the elbow out; is this not actually using the shoulder as a fulcrum? You are exerting force, this time from the arm instead of from the body, on the elbow which pivots on the shoulder through the arm.
