I believe you're confusing the two domains - someone please correct me if I'm wrong, but wasn't bitcoin.org registered by Satoshi while bitcointalk.org was registered later on?
The bitcoin.org domain was already registered when Bitcoin became public.
The source I mentioned above confused me. You right, bitcoin.org was registered by Satoshi Nakamoto and Martti Malmi. Later he gave the ownership of the domain to someone else. Source
Who owns bitcoin.org?He registered it through anonymousspeech.com
