Correct. There was a paper published a while back (I wish I could find
a reference, but my google-fu is failing me right now) that showed
enforcing strong passwords and frequent changes reduced overall
security, among other reasons because users tended to write them down
rather than remember them.

Also, in this situation, changing passwords at all on the system is
madness. The only sane option is a complete reinstall (yes, using
different passwords). You don't know what the intruder has left on
your system. A fresh OS install and a scan of your data for hidden
nastiness is needed.
