Not a journalistic investigation, but a while back I decided that I need a new gmail account. I signed it up using some different credentials, including a different name. However, I did not mention my old gmail account in the entire sign-up process. After I activated my new account, I got an email on my old account referencing the new address I just signed up for and a verification code "in case something happens."

From this it seems to me like this is not a deliberate maneuver to deceive, but rather just an oversight.

I have a second gmail account (in the olden days that's what they recommended on http://code.google.com/apis/gadgets/docs/publish.html - I see now that they have switched to using filters), and this didn't happen to me.

Are you sure you didn't use the first gmail account to send an invitation? Because in that case it does add the address to both accounts address books.
