Yeah. I do use this trick.

Some "root" passwords are ones I do not put in my password manager out of "what if my pwd manager gets compromised" paranoia, but that makes me more vulnerable to this.

And annoyingly some websites like to forget you're logged in. Not Google as much, but it's a thing that happens enough that means that there's a chance that I would blindly enter a password if my guard was down. A slight chance I think (especially in the last year where i've been worried about more sophisticated scams) but a chance nonetheless.
