The questions Why does Meta Stack Exchange have privileges that don't have any effect? and Meta Meta Privilege were both marked as duplicates.
However, one of them has a different "marked as duplicate" notice below from the other. The first says "This question was marked as an exact duplicate of an existing question", and the other one says "This question has been asked before and already has an answer".
I thought that maybe the messages were different because one of the questions is mine and the other one isn't as explained at Why are there two different duplicate post notices?, so I logged out and saw that there were still two different messages:
There are two differences that I noticed. First of all, the first one was closed by someone who had a gold badge in one of the question's tags, whereas the other one was closed by five normal users. Second of all, the first closure is much more recent than the other one. Is the reason to the different wording one of these? Or is there another reason?
Why are there two different duplicate notices? What is the difference between them?
This is not a duplicate of What decides what to prepend the duplicate question list with on a duplicate question?, as that question asks about the link to the target question above, while mine asks about the "marked as duplicate" notice below.
