I dunno about 5.4 but I believe the "postuser" [assuming that is where
your "shared" thinking comes from] is only used to allow posting [via
LMTP?] directly to a shared folder.  I didn't/don't think it indicates
the actual namespace of non-user folders.

Perhaps this relates to a RoundCube bug
<http://trac.roundcube.net/ticket/1403507>?  RC's bad folder management
is pretty well known.
