The answer for the question How do comment @replies work? states the following:
For questions: The moderator or gold badge holder who closed or reopened the question, provided they were the only one to do so. Users who have closed or reopened a question without a binding close vote (i.e. without a gold tag badge or a moderator vote), and those who bindingly voted, but other users were also involved (e.g. closed by User1, User2, and Moderator) cannot be notified.
It's not quite clear for me, does a gold tag badge holder get notified from a comment via
@ if for instance they are second person who voted to close/reopen?
