I shall answer that question.
There is actually a very specific reason. Say that you have MSE set to auto-install updates at 14:00 every day (actually set by auto scan at 14:00, and update before a scan). Say that Microsoft happen to release an update at 8:00, and you happen to check Windows Update at 10:00.
The MSE definition updates will be shown, but are marked as optional because if ignored they will be installed within 24 hours (at 14:00 in this example)
I know they are a bit disconcerting, I know how you feel, but they will auto-install given time.
