Your expected and actual behaviour are described above, but it is
not mentioned out of what command (and in what settings) you expect
the above behaviour.

I am guessing that the setup and the command is something along this
line?

    git checkout not-the-master
    work work work
    git rebase --autostash upstream master

That is, you have checked out a branch that is not the 'master'
branch, you have accumulated some work in the working tree, and then
you ask "please stash away the work in progress and then rebase the
'master' branch on top of the upstream branch"?

If so, my expectation for the third step (i.e. the actual "rebase")
aligns with yours.  After stashing away the local change, we want to
get a clean working tree, checkout the master branch and rebase it
on top of the upstream.  With the command sequence you wrote in the
"actual" section, after stashing away the local change, the current
branch that is *not* the master is reset to the tip of 'master',
which would not be what we want.
