The sense given would perhaps be clearer if we were to read (as Gulonius seems to have done) ἀσυνήθη for συνήθη. This might be interpreted, “He could not say, I take it, even if he uses the words in an unwonted sense, that the Son is at variance with Him Who begat Him.” The συνήθη would thus be the senses already considered and set aside: and the point would be that such a statement could not be made without manifest absurdity, even if some out-of-the-way sense were attached to the words. As the passage stands, it must mean that even if Eunomius repeats his wonted phrase, that can suggest no other sense of “variance” than those enumerated.
