I think the takeaway from this is just that classification of phenomena into these triads is a very subjective business. That's not necessarily a bad thing, since the point of this (if I'm reading Yvain correctly) is not to determine the correctness of a position by its position in a triad, but simply to encourage people to notice when their own thinking is motivated by a desire to climb the triad, rather than pursue truth, and to be skeptical of yourself when you detect yourself trying to triad-climb.
