I don't usually have any issue with stack exchange moderators, but in this situation I really don't understand why my question was closed. The reason listed is "unclear what you are asking," but the question is clearly stated. Why was my question closed?
The closure shouldn't be unclear what you're asking, but instead it should or could be too broad because it is clear what you're asking.
In this case, the moderator's intervention was a bit inappropriate, especially that your question has been answered.
However, the moderator has a point: Your question ("claim") could apply to too many universities and universities in different countries, that would nominate your question for being too board.
