Sounds vague and intentionally scary. What exactly was "leaking" in incognito mode, when it does not share cookies or other similar data with main browser? Incognito is like installing and launching another browser in which you are not logged into any of your accounts. What would "leak" there?
Don't know but I guess it just cross reference the IP address via cross site scripting/ time stamps. Google can fetch your browser history from probably 15 years back without even requiring you to login even if you used different computers this way as long as they have something to correlate with.

Dunno...Why would they even care!?
