If I was a cryptographer with a nym, I'd also be sure to document the story of my involvement from my "true name" just so there's testimony that provides evidence of separation of my identities.

There's precedent for anonymous founders using their alternative accounts to spread awareness of the project. The first username to mention the Silk Road belonged to Ross, for example.

Plenty of nyms are involved in the same company or organization as their true identity.

Just observations. Satoshi is whoever you want him to be. That's the beauty.
