Of course, but which superposition? People interpret ud-du by a superposition of ud with du, but it can be seen as superposition like u’d -d’u, et Alice can choose the partition of the multiverse, which is indeed greater that any simple superposition. You need to add perhaps that the prediction is independent of the base, and that follows from Everett theory. We just don’t share the interpretation of the universal wave. But your’s and Bruce remains quite unclear to me, and seem to impose some favorite base, which, especially in this case, cannot work, or Alice becomes overdetermined or superdetermined (which I doubt).
