What should we keep in mind when using the [reopen-closed] tag?

My closed question #1 on SO:

• How to slow down the scroll speed in Microsoft Edge using JavaScript?

The reason it was closed was outright wrong IMO, so I posted on Meta:

• My JavaScript question was closed for not being about programming

This was immediately closed for not being suitable for Meta.

So what is the point of the reopen-closed tag?

I read the description of it before posting, and it seemed to be perfect:

A request to have a specific question reopened by the community, often resulting in explanations why it was closed and guidance on improving it.
