"deny duplicates;" not working?

I do use class and subclass, something like:

class "gateway-1" {
         match hardware;

allow members of "gateway-1";
...... other options;

subclass "gateway-1" 1:00:04:20:17:fd:6d;               # host Sq-rcvr
subclass "gateway-1" 1:00:04:20:1b:d1:1c;               # host Sq-control

This is instead of using host statements, with "spawn" there is a spawn
statement in the class instead of the subclass - if I understand correctly.
