Thanks all for following up.  After all I've installed the following
user option and the code in the Gnus trunk.  This does not change
the present behavior by default.

(defcustom gnus-mark-copied-or-moved-articles-as-expirable nil
  "If non-nil, mark articles copied or moved to auto-expire group as expirable.
If nil, the expirable marks will be unchanged except that the marks
will be removed when copying or moving articles to a group that has
not turned auto-expire on.  If non-nil, articles that have been read
will be marked as expirable when being copied or moved to a group in
which auto-expire is turned on."
  :version "23.2"
  :type 'boolean
  :group 'gnus-summary-marks)
