Thanks Moritz and sorry for not adequately describing the situation.
The scenario is much simpler; imagine master has a longer history behind
the point where the topic branch started:

                A---B---C topic
               /
  *---D---E---F---G master

And we want to keep both branches separate (no desire to merge them for
now), but we realize that, say, commits D and E should be
squashed/fixup, so we do an interactive rebase.  Now, the problem is
that if I do that from the topic branch, the results are not reflected
in the master branch, even though these commits are certainly shared
with master.  It seems counterintuitive that a part of history that is
shared among branches can be independently manipulated/rewritten with
rebase.  I must be missing something...
