Identity is not what prudentially matters in survival (this is originally and most famously argued in Parfit 1984, 245-280). Consider the case of division. a is one of three identical triplets. In World 1 his equipollent cerebral hemispheres are removed from his head and each is inserted into the (suitably emptied) skull of one of his brothers, resulting in the existence of two persons, b and c. In World 2, only one of his hemispheres is transplanted (while the other is destroyed), resulting in the existence of b*. Note that, assuming the necessity and transitivity of identity, b* is identical to neither b nor c.
