When you log into Google, you also log into Chrome. This means that you'll have a lot of exceptions for Google websites or else a "clear history" would log you out of Chrome.
Not justifying it (I don't use chrome) but that's likely what's happening here.
This is what the “Allow Chrome sign-in” setting is for and is turned off by the post author.
In the article he explains he’s not signed into Chrome nor Google during the experiment.
