Correct.  And I've been meaning to post the same question for awhile
now:  How to have message expiration in a folder and *not* for its
subfolders - short of setting an additional annotation on each
sub-folder (which in our circumstance isn't workable as the user can
create additional subfolders).

My guess, is no.  FYI, purge exhibits the same behavior [as documented].
