For proper explanation, I believe it's worth discussing git ref, git head, and git HEAD:
git ref is simply a pointer to a commit. git head is a ref that points to the tip (latest commit) of a branch.
Similarly but differently, git HEAD is a special ref that points to the commit you are currently working on - the currently checked out commit in your Git working directory
That way, it might be a bit confusing and mistaken of the tip/head of a branch and a current actively branch.
Hope this helps!
