Not really. Because it's a WEBSITE feature and not an IE feature your autocomplete has nothing to do with it. You can go to a login website for the first time with autocomplete enabled and check that box and still get the popup. They have absolutely nothing to do with each other, nothing about that checkbox (or dropdown on FR) has any effect at all on the behavior of autocomplete or vice versa. Here's an example of the popup and the dropdown both happening at the same time completely unaware of each other:

I don't have a problem. You on the other hand have now fully established that you have absolutely no idea what in the hell you're talking about. You think website cookies and IE's autocomplete feature have anything to do with each other at all.

Auto-complete has everything to do with it. Even if you select the option NOT to remember your password, when you visist the site again, all you gotta do is click the box for “userid”, and your userid just appears in a drop down list.
In addition of course most sites give you the option to let IE8 remember your password, so that whenever your point your browser at that site, you are automatically logged on. After you have you click your “Remember my password” button+userid+password, then click your "Login" button, you are logged in straight away, with NO POPUPS, like this:
