How does GitHub Pages detect pull requests to be auto-closed

Hello.

How does Github Pages detect pull requests to be auto-closed?

I think that it is the same processing as [git branch --merged](https://github.com/git/git/blob/master/builtin/branch.c#L110), is it right?

Some pull requests is auto-closed.

Some cases like Example2 does not auto-close pull request.

Example1: <font color="#000000">add_aaa is auto-closed

I create two pull requests

• develop (base: master)
• add_aaa (base: master)

If I merge develop to master, add_aaa is auto-closed 

  

Example2: <font color="#000000">add_aaa is not auto-closed

I create two pull requests same as Example1.

Even if I merge develop to master, add_aaa is not auto-closed.

I think the reason is that you can not trace the commit graph from the master (after develop is merged) to the head of the add_aaa branch.

Thanks in advance for your help!
