I would guess he concerned himself more with stems than surface form.

  Except "fill" is allowed, but "filler" is not. I think he cheated.

    Depending on context, filler is a much more complicated concept. You could be referring to stuff they put in food that is not food, or stuff they put in cracks to fill them in, or a nozzle at a gas station. By contrast, go is such a foundational word to English that it appears in English reading primers for toddlers, and a goer goes.

      grow, grower. The point is, he's not simply stemming. He cheats.

    If he uses regular rules for allowable modifiers (e.g., "-er" can be added to a verb that is in the base list, to form a noun that is refers to the agent of the action described by the verb, then "filler" would be allowed if "fill" but not "filler" was on the list, but only to refer to the actor who causes something to be filled, rather than thing with which something is filled.) I certainly think its clear (and even implicit in his own descriptions) that the exact methodology is not disclosed, but I don't think its far to say simply "he cheated".
