Interesting, but likely not genuine. Satoshi's identity, even if he didn't get ganked in prison after authorities around the world collectively throw him/her/them in jail and throw away the key, would likely destroy Bitcoin as we currently know it. All that the Bitcoin bugs would care about is whether Satoshi supports BCH or BTC, and no matter what answer Satoshi would give, there'd be someone angry. Also, knowing the identity of Satoshi at this point would possibly create a black swan event in global politics.
