Yes you are correct. If they tried to make a post, Vbulletin would spit out a MySQL error notifying you of an error with that query.

When using a lock, it prevents any threads from doing a write to that table, that is to keep consistency while you are doing the backup.

Note: I strongly suggest to use the lock options & the shutdown option. Just make a pretty message to be displayed, notifying your members its just routine backup procedure.
