It also means you can do XXX-YYY(stop in AS hub/CX gateway)-HKG(stop because of Avios)-RGN if you please. It's possible to use the stopover NOT in HKG, but it would have to be in an AS hub/CX gateway, like SEA/SFO/LAX. I've done LAS-SEA(stop)-LAX-HKG-BKK and HKG-LAX-SEA(stop)-DCA on AS partner awards.
