Elaborate? What is the impact of this random behavior for the-in the case of the analogy before us-an administrator? Doesn't Chrome's autocomplete, in the case of credentials know which credential belongs to what password?
If an admin goes to log into gmail on an end user machine, and enters his email address, why would the user's password pop into the password field?
The admin visits a page to edit a normal user on their website, which contains fields like email/password etc for that other user.
Chrome autocompletes the admin user's password and email in the form fields without user interaction. There was no mechanism to tell chrome not to do this if autocomplete=off is ignored, but you can set autocomplete to an arbitrary value (say =nope not =off as in spec) and it will not autocomplete.
I've seen this on real sites and had users complain about it, it is a very real issue, and unfortunately not all admin users are savvy enough to turn off autocomplete in just one instance, when they use it all the time elsewhere (even on the same website). It's nice if the website can somehow fix this by saying they really don't want autocomplete on a form to edit other users.
Personally I think the browser should give the user control, but autocomplete should not be the default if the website requests it to be off, it should be available on right click or with some easily accessible option. This should satisfy everyone and avoid situations like the one described above where the user sees arbitrary and incorrect values being filled in a form which is not related to their user and is not a login form.
Let me ask a quick question because after reading your post I think a lightning bolt just struck my brain, and I went and read other comments:
Have I been confusing autocomplete with auto-fill this whole time? Autofill where, let's say you shop on a site often, and you fill out one form field, select a saved entry and the rest of the form fills out?

I'm afraid I don't understand your counterpoint.
