Hello Ron,
both terms refer only to the orientation of the laminations. The surface treatment isn't covered and would depend on local Indo/Malay traditions.
I agree that utilizing central Javanese definitions/words for Moro kris is not optimal. However, the same could be argued for neighbouring cultures like Sunda in W Java. OTOH, the Jawa terminology is widely known and de facto lingua franka throughout the keris world nowadays with local terminology regrettably lost to time way too often...
