ATC are entitled to assume the codes for pipeline helis and police have already been validated and their altitude readout verified by the unit they were working previously; I would assume they want controllers to assign a discrete code to aircraft previously using a conspicuity code to show other units the aircraft is actually talking to an ATC unit rather than just listening out.
