It means nothing if you ask me since it is already too late. It's not like he needed that much time to figure it out! It takes a second to know if someone is lying when they can't provide any kind of proof not 7 years. I don't buy the NDA thing either since he could have not-say he is Satoshi in first place!
Something definitely shady is going on behind the scene between Andresen and Wright and in my opinion the only reason why Gavin went back on his words is the fallout between them, possibly Craig scammed him or refused to pay the money he promised Gavin after his support or something similar.
