I was able to get a bit more information by watching machines as they
run the updates. I have found XP machines here that have AU turned off,
yet have the updated files (big surprise). I have also found some
machines that did not yet have the stealth updates. When updated using
the WU website, it does not update the WU files until you get to this
screen and click on this button (see screen shot at below link), so
through this method you actually are prompted:

If you have a machine which has not been updated yet with the stealth
updates, and AU is turned off, then you turn AU on, those files will be
updated without notification to the user before the bubble pops up from
the systray stating updates are available.
