My take on that LL is that it is a method of controlling the aircraft, not a procedure.
To try and expand on that a bit; there is a ‘procedure ‘ for flying a circuit, but that procedure doesn’t specify exactly how you control the aircraft, do you do it with the AP engaged? Flying manually? In CWS pitch and roll? Just CWS roll? I think this is similar, not a procedure, just a method of carrying out a procedure, and that when the functionality of the machine changed, the crew needed to be briefed on it and informed of any fish hooks associated with the new functionality. This may well have happened, I don’t know, but if it did I think the report would probably have mentioned the method of promulgation.
