One possible interpretation of "if I always cooperate, what would happen if I don't" is "what is the limit, as X approaches 1, of 'if I cooperate with probability X, what would happen if I don't'?"

This doesn't reasonably map onto the 1=2 example.

Right. There seems to be a discontinuity, as the limit of CDT (p->0) is not CDT (p=0). I wonder if this is the root of the issue.
