That's an interesting theory and it might be nothing but I heard that the voice was different in the japenese version. I'm guessing it's Big Boss, who according to the begining of ground zeroes is again known as Snake accoding to his description at the beginning. Plus I think Hideo or someone has said that Punished Snake is like Old Snake he's Big Boss like Old Snake was Solid Snake, it's just a reference to the period of time or what's going on in their lives at that point. But of course whoever said that could've been wrong or just misleading us.
