Even that doesn't guarantee anything.  Clients can and do still suggest and receive a different lease length.  Its really not often, but I have seen it.  For example, some versions of windows will initially request an hour lease followed by a full lease length (ie: what you have configured in your directives) at renewal time.  This would be when you have longer than an hour lease lengths configured.
