One thing that is not made clear in the article, is that there is a separate reflog for HEAD, and separate reflogs for individual branches.

HEAD reflog logs changes such as "checkout: moving from next to main". Branch reflog logs changes such as "branch: Created from HEAD" (first entry in branch reflog). Most are common to both (i.e. git logs both to HEAD reflog and the reflog of currently checked out branch).
