A simple answer and a more elaborate one.

 * It is the final step of "git rebase" which detaches HEAD while it
   operates these days.

 * You can drive sequencer backend from a front-end that rewrite history
   while rewriting tags, like filter-branch does.

That is not very important question, as reflog updates would happen as
long as you use update-ref automatically.

Much more important question you did not ask is how it would interact with
"sequencer --abort".  Ideally it should rewind the ref update (and without
relying on the user having reflog on that ref).

I however personally feel that this "ref" thing is being a bit too
ambitious.
