Hmm. That's not quite the right description of the illogic but something very odd is going on:

Suppose I find A and B incomparable and B and C incomparable but A is preferable to C.

Joe is willing to trade C=>B and B=>A.

I trade C into B knowing that I will eventually get A.

Then, I refuse to trade B to A!

But if Joe had not been willing to trade B=>A, I would not have traded C=>B!
