That's a very good point actually, you're right! Although one thing that I do wonder about is that Rayleigh mentions Gol D. Roger had the "power to hear all things". Perhaps this was Kenbunshoku-Haki too so it might not be limited to just living things? But hey, there's no way of telling yet, we'll have to wait and find out!
