Dorian Nakamoto is Satoshi: This is an attempt by him to throw people off his scent, which would be foolish and desperate since chances are the millions of eyes focused on him will find more concrete proof than the Newsweek article, rendering the posting moot. Almost guaranteeing the drama will continue, if not whip it into a larger frenzy.
Dorian Nakamoto isn't Satoshi: An attempt to absolve someone of harassment. Noble, but not wise, since now he will have to continue to disprove serious accusations of his identity, or else innocent people will be harmed again. And the corollary, if he does not publish a refutation people will assume it's tacit agreement. People will continue looking for him.
It's late and I know I didn't think of everything, but I can't see this being a winning move by Satoshi in any scenario.
My personal theory? Dorian was a member of a crypto group that eventually gave birth to Bitcoin, but he was never part of the implementation. Maybe he thought of the original math/idea, so they named their pseudonym after him in his honor? Probably not true, but fun!
