This is a nice example of a user that does not quite understand what google does here. It uses the history of the user and displays a site recently visited as one of the results.
So, google does what you want because it remembers what you wanted before.
So much for the 'I don't'.
Open a new incognito window and try. Its the same!
Do you actually believe that an 'incognito window' makes you invisible/untrackable or something like that?
