This question https://tex.stackexchange.com/questions/194028/export-image-as-eps-but-pi-symbol-changes-in-matlab was in my
Close Review queue. I voted to leave open.
The post mentioned is just an example, I do not refer to the content of that post at all.
After some time, there were 2 close votes visible on the post
I was curious if I could still vote for close, although the question was already in the queue and I voted as mentioned.
The answer is: Yes, it is possible to vote for close! I did that, but retracted it afterwards.
Why is is this possible? As a chance to think again about a previous
Leave open vote?
This question is somehow related to What is the difference between these two kinds of close votes?, but is not a duplicate, in my point of view.
I added some screen shots to show the proceedings...
