I'm very confused by your comment. The grandparent comment talks about using the gitrevisions syntax in a GitHub URL to search the reflog stored on GitHub. Nothing to do with your local clone of a repository.

Yes, I refer to the reflog on GitHub’s git file servers which tracks the historical state of refs there.

I'm sorry, I was on mobile and for some strange reason didn't check the whole link. I guess I was tired.

Incredible, I didn't know about it.
