Yesterday I flagged my [own][1] post as exact duplicate of [this][2] post.

It got a result of *none*.

>![enter image description here][3]

Then, I thought that it was not a dupe that it might had some unique details. But, today morning I saw that the post was closed as duplicate as I flagged. 

What actually happened? I need clarifications on that. If it's a duplicate question means my flag should be accepted as helpful. but, it returns the result *none*. What does it mean? Then after long time(about 4 to 5 hours), the post was closed as duplicate. I got confused.
