If I understand correctly, under MW you anticipate the experience of surviving with probability 1, and under C with probability 0.5. I don’t think that’s justified.
In both cases the probability should be either conditional on “being there to experience anything” (and equal 1), OR unconditional (equal the “external” probability of survival, 0.5). This is something in between. You take the external probability in C, but condition on the surviving branches in MW.
