Sometimes an update happens quickly and is not time-consuming, so you don't see a progress screen. It depends on the update, some will be quick, some will be slow. If it's quick it might look like the computer quickly shut down without updating, when it fact it updated fine.

Sometimes the time-consuming part of the update occurs at the next bootup rather than the shutdown. So you don't see a progress indicator at shutdown, but one appears at bootup (while you're away getting your coffee).
