For what it is worth, I have received a number of these over the last few months. I've never been able to get any word of explanation from the google. Apparently part of their new policy of "All your attention is belong to us (the google), but we don't pay any attention to you" that replaced the now sad old joke of "Don't be evil."

In the absence of any real data from the google, I have two theories. The less plausible one is that there is some kind of technical booby-trap on the new account. In that case, clicking on any of the links might be enough to detonate it. If so, the scammers are quite sophisticated, perhaps too sophisticated for the google to deal with the problem, which might be why they refuse to talk about it.

However, I think the more likely possibility is that the attack is some kind of social engineering thing. They want to get you involved with the new account in some way, and then they are going to trick you or trick your contacts and friends into communicating with the fake account. Or maybe they have a backdoor for some kind of password reversion trick after you've been tricked into using the new account.

Whatever it is, it stinks to high heaven and I am completely unable to imagine a scenario that would give it enough plausibility to call for an explicit disavowal.
