Mostly, yes. It also covers changes to the working copy (because jj automatically snapshots changes in the working copy). It's also much easier to use, especially when many refs were updated together. But, to be fair, it's kind of hard to update many refs at once with Git in the first place (there's `git rebase --update-refs` but not much else?), so undoing multiple ref-updates is not as relevant there.
