The superrationality explanation still makes sense. If the other player’s choice is known, then symmetry is broken, so the superrational agent should defect.
Other than that, I’m not really sure what you mean by “explanation”. The “folk version of superrationality” sounds plausible, but the underlying causes of the experimental results still feel pretty mysterious. Demystifying them is well beyond my capability, but it’s certainly an interesting question.
