Ah sorry, misunderstanding. 

rectify-zone is needed in order for powerdns auth server to understand your zone data properly. 

The slaves will accept notifications, if you have configured them to accept ns4 as supermaster.

This behaviour is most likely due to the fact that pdns will detect zone change after rectify and sends notification to your slaves. 
Rectify command itself does not emit notifications. 

ALSO-NOTIFY can be used to notify arbitrary IP address when the zone changes.
