The problem is that range isn't the only thing that will break that connection; swimming will, occasionally a shower will, body positioning will do the same (so when I'm cuddling with my girlfriend my watch begins to vibrate), as will the phone acting up or dying. It's a good idea in theory but it happens too much in practice to be useful.
