That doesn't mean much. They could still correlate and combine information with any anonymized (or rather, what they consider anonymized) personal info. The fact that they even mention that they have permanent logs is quite unsettling. I would think they'd just dump the data from all of their services into your advertising profile. They won't store your name and such, but they have to have a way of linking this anonymous profile to your google account or something. I doubt that google simply deletes all advertising profile data if you just happen to clear your cookies.
