"And I reasserted, We are talking about Bitcoin here, correct?"
and he said: "what is bitcom?"
and i said: "you are satoshi right?"
and he said "yes, go away!"makes sense.

When you watch this video:
http://www.youtube.com/watch?v=GrrtA6IoR_EIt's abundantly clear Dorian is not the creator of bitcoin.
Especially the end, "Leah wrote this?" Dorian says before shaking his head in disbelief.
I tend to agree. Either the creator of bitcoin is also a world class impromptu actor and amazing liar or this is just a smart old many living his life in retirement with no idea what the heck bitcoin is.
And yes that reaction towards the reporter is very convenience, its a reaction of just complete shock.
