If you were the real Satoshi, and you took your anonymity seriously, why would you particularly care if the press had descended on some other fellow? If the world decides the wrong man is Satoshi, the real Satoshi(s) could breathe a lot more easily.
Satoshi sticking their neck out to keep the hunt alive would only exacerbate the side of the bitcoin story that they've been trying to avoid and downplay for quite some time.
Also I think that if the creator of Bitcoin had really wanted to clear Dorian's name, he would have used something like BTProof so that we know the exact time at which it was posted. If Dorian was known to be not behind a computer at that time, it is at least a much stronger indication.
