I'm afraid you are making a mistake in assuming that Incognito mode == no tracking. The only thing that Incognito mode does is not save any local history or cookies. This is mainly of benefit for people who share a computer and don't want the other users to see their history.

Tracking has long moved way beyond cookies and Google is absolutely tracking what you do in incognito mode and doing their best (which is highly effective) to associate the tracking data with you.
