It's common in the BBQing/Smoking communities to use bacon strips over other meats. Turkeys, meatloaf, even other pork products. I've always seen it as a "self basting" of fats and flavors to the end results. Does it go from exterior to interior? Probably not.
I could imagine external fat penetrating ground meat. I have a hard time seeing external fat penetrating the (hydrophilic) intact muscle in a piece of meat that isn't ground.
