It appears that once a colonist corpse gets moved to a corpse disposal zone they will not be moved to a colonist grave until you delete (or move away) the corpse disposal zone. This means colonists only get moved to graves if the grave existed before they died if you have a corpse disposal zone, and I expected the corpse disposal zone to work more like a stockpile.
