Perhaps a link could be provided from the Help to this answer to What exactly happens with the button "Leave Open" (previously "Do Not Close")?
Normally, a question must hit 100 views before close votes age away,
so as to give enough folks time to see and review it. Questions with
close votes stay in the review queue until they are closed or the
votes expire.
But if enough people (currently 3) select "Do Not Close" within the
review queue, the question will be immediately removed from the queue
(not shown to any more reviewers) and the aging starts immediately.
Alternatively, with a little more detail added, this answer to What are the review queues, and how do they work? could be used but it currently seems to fall similarly short on detail:
Finally, you can also choose Leave Open (or Leave Closed in the reopen
queue). What does this last option do? If enough people vote to leave
a question open or closed, the question is removed from the
close/reopen queue (respectively) and immediately begins aging the
existing close or reopen votes on the question (it does not clear
them).
