Why was the question about adding "let me know if anything is unclear" to an email reopened?

Question

Yesterday, the question Is adding “let me know if anything is unclear” to an e-mail really necessary or is it redundant? was closed, with a link to the meta answer of Tinkeringbell, where she explained nicely why the question in it's current form was not fit for IPS.

Six hours later, the post was reopened again, with no edits.

So I want to know what happened. I see 3 possibilities:

1. The reviewers didn't agree with Tinkeringbells explanation and voted to reopen it anyway. They did not vote down her meta answer (it was +7/-0 today morning / 3 hours ago).

2. The reviewers didn't look at the meta question that I linked to in a comment, specifically for the reviewers to know why it was closed. They also thought that the question was okay

3. The reviewers didn't read the question, and just pushed some buttons.

There are problems with any of these actions, some are more harmful than others. In any case we should probably try to do something about it.
I would like to find out which of these it actually was, so that we can address the underlying issue.

_{I am not trying to find guilty people to punish. I don't want to scold any of the reviewers. This is about the underlying issue, how this could have happened and how to prevent it in the future. Reviewers please don't be scared to speak up!}

Answer 1

I expect the main problem stems from the (perhaps overly) detailed strictures on what constitutes an "interpersonal skill". Reading Tinkerbell's answer, I was surprised to see this:

Writing etiquette is different from social etiquette, writing skills aren't interpersonal skills.

Uh ... come again? Yes, I can see the argument here but to a new user like me, this kind of distinction is not at all obvious. Yet, despite my neophyte status, I still have been granted the privilege to cast close/reopen votes.

My solution: Raise the bar. Require a much higher reputation to cast these votes, to at least attempt to ensure that those who do vote are familiar with the ongoing discussion about what is or is not off-topic.

Alternately, revise and simplify these restrictions so that this forum doesn't require a meta-meta-"Sandbox" in which to "test out" potential questions. But I suspect that's a pain-point that deserves its own discussion.
