Is there a delay between edit and question appearing in Reopen Votes review queue?

Question

According to this question & answer, a question should appear in reopen queue less than an hour after an edit. However, I noticed that most of the edited questions in my review queue have last edit a few days back. I'm talking about the questions with reason "This question was edited after it was closed." Why haven't these questions appear in my review queue earlier? Are they intentionally delayed or it is a bug (i.e., they are there because of reopen vote rather than edit) or something else I don't understand?

I.e., this question just appeared in my queue, while it has been edited a few days back.

Ok, so to understand how this question ended up in the Reopen Votes queue again, you need a bit of a timeline of events that a normal user would not really have access to see (anonymized, of course):

Now, as you can see, the question received two reopen votes. One occurred during the review process, and one occurred after the review process had already completed. Understanding the process of expiring reopen votes, it takes 4 days from the last reopen vote for the oldest vote to expire. So, on February 2nd when the 3am process ran, it expired that first reopen vote, and left the system with a dilemma:

It now has a new reopen vote that occurred on the question outside of the review item's window. That means it needs to be bumped into the Reopen Votes queue again so that the question can be reviewed (again). It just had to wait for that other reopen vote to expire before it could do that (if it were to keep receiving reopen votes at a rate of at least 1 in fewer than 4 days, it would get reopened without need for review). If the second reopen vote had occurred inside the review queue as part of a review, a second review would not have been necessary; it wouldn't bump back in for another reopen vote until after all those votes that occurred inside that review had expired.

So this question actually entered the Reopen Votes queue because of another reopen vote, and it was actually the second time it had been in review (the first time was for an edit).

Also note: This is unverified, but I remember reading somewhere that an edit can only bump a question into the Reopen Votes queue once. Further edits would not continue bumping it into review. I could not find a source for that, though.
