That's in the approximation in which separate worlds are orthogonal - something they only approach asymptotically (unless my speculation that there is a smallest unit of probability is true). The amplitudes of the projections onto these almost-orthogonal subspaces is interpreted by the Born axiom as being the probability of that "branch". But I don't believe this can be proven to follow from the other axioms of QM; it has to be assumed separately as part of the formalism.
