Looks like this is a special case for when you close as a duplicate of another question that doesn't have any upvoted answers.
On normal sites, normal users can only vote to close as a duplicate if the other question has an upvoted or accepted answer (moderators can bypass this). On meta sites, however, any question can be closed as a duplicate of another question, no matter if it has answers or not. So naturally you'll see this possibility a lot more on a meta site than on a main site.
