Linking Dorian to Bitcoin at any time proves everything, proves Dorian = Satoshi. If Dorian paid for crepe in July 2011 with Bitcoin, Dorian is lying and Dorian = Satoshi. There was a large Bitcoin Conference in New York at that time, giving good reason to be there. The retailer said she recognized Dorian as the customer. He didn't want his picture taken or name recorded. Good odds to me it was him.
You say "good memory," but there's no evidence of it. The post said "recognized him," though there's a bit of priming (A NEWSWEEK COVER STORY!) to encourage that process along: https://news.ycombinator.com/item?id=7354326
Memory is highly fallible. Eyewitness accounts are highly unreliable even after a shorter period of time than three years. The burden of proof is properly on the Dorian == Satoshi folks.
That is the most spurious logic I have encountered all week. Dorian lying about the specifics of his involvement with bitcoin does not logically imply that he must also be lying about not being Satoshi.
Even if Dorian is lying about knowing what bitcoin is, I think it wouldn't be a proof of Dorian = Satoshi. He might be worried people would dig his personal life more if he acknowledges he knows what bitcoin is.

And "large volume" = 432,000 coins.
