I'm happy to be wrong here, and I'll give it more thought to see if I can figure out where this would reproduce otherwise.

You can skip the first amend and use revert to achieve the same 
changelog//filelog topology divergence:

   $ hg init repo
   $ cd repo
   $ touch a0
   $ hg add a0
   $ hg commit -m a0
   $ hg mv a0 a1
   $ hg commit -m a1
   $ hg up 0
   1 files updated, 0 files merged, 1 files removed, 0 files unresolved
   $ hg revert --rev 'desc(a1)' --all
   removing a0
   adding a1
   $ hg ci -m 'a1-msg'
   created new head
   $ hg mv a1 a2
   $ hg status --copies --rev 'desc(a0)'
   A a2
     a0
   R a0
   $ hg ci --amend
   saved backup bundle to 
$TESTTMP/repo/.hg/strip-backup/ce7fa13c3beb-amend-backup.hg
   $ hg status --copies --rev 'desc(a0)'
   A a2
     a0
   R a0

resend was not really necessary since we still have the obsolescence 
bits to solve.
