He wouldn't be the first one to do something great and then avoid credit; only to secretly want to be "found out" someday.  Think about how people make secret donations to charities and then get outed.  How can anyone truly cut all ties with the possibility of receiving credit for their work?  I think Dorian got spooked when the media point him out as Satoshi because the statement is too definitive; he wants to tied to the project somewhat but wants to remain murky.  Whether Dorian is the creator nor not, I think he realized the possible negativity the fame could bring and therefore denied everything.      Who the creator really is and what he intends to do with the genesis blocks is part of the mystique of bitcoins and therefore I personally do not care to find out the creator anytime soon.
