Sure, that is the best case scenario. Apple using it's own servers would have several advantages including they would presumably be able to tune/seed the cached content based on superior knowledge of consumption. They also wouldn't be competing for the same limited CDN space as others.
Not to be flippant, but I recognized your name and when I visited your bio I see you now work at Netflix. You could probably find an excellent answer as to why Apple would choose to start its own program rather than rely on existing CDN colocation by asking your internal team why Netflix does the same. My guess, without inside knowledge, is it is a combination of price and performance.
