I somehow do not think this is a version difference.  Assuming that
your default remote is called "origin", I suspect that you have
refs/remotes/origin/HEAD symbolic ref in the repository you use with
Git 2.50, while in the other repository you do not.  Both versions
are capable of showing that symbolic ref information.

You can try in the repository where you use Git 2.43

    $ git remote set-head origin -a
    $ git branch -a

to see if the difference indeed is coming from different versions.

Scripts should be reading "git for-each-ref" output in the first
place. Output from "git branch" is meant for human consumption and
is subject to change any time (even though in this case I suspect it
has not changed.
