You're misreading the privacy policy. Google's privacy policy has two modes, one for sync on, and one for sync off. Logging into Chrome does not turn sync on, so you can be logged into Chrome and still covered by the "basic" privacy policy.

They aren't actually collecting that data because you haven't turned sync on.

Yeah, well, but what keeps them from silently changing that, seeing that users are already logged in? The UI for the sync preferences is sketchy at best as it is right now and you're basically just one misclick away from handing all your browsing data over to Google.
