Im not seeing anywhere in the quest where he is triggered. It just says find him in Ferubi. Found him in the SW room of the zone. Wanders within the room.
Smith Rondo is regularly an Erudite, however if a raid has failed the encounter beforehand and spawned him, he will appear as an Ukun, as he never reverts back to his original appearance. I guess it's just something SoE overlooked while designing the encounter.
