There is nothing irrational about choosing 1A over 1B or choosing 2B over 2A. Combining the two into a single scheme or an iterated choice are totally different situations from the original proposition.
Too much research on cognition, especially biases, tends to infer too much from simplified experiments. True, in this case many people slip into a money pump situation easily, but the original proposition does not require that to occur.
