I am talking about Quantum Mechanics without collapse. You are the one seeming to interpret ud + du as a superposition of worlds with Alice having a particle in state u (and Bob having the corresponding particle in state d) with worlds with Alice having a particle in state d (and Bob having the corresponding particle in state u). That would contradict the rotational symmetry of the singlet state.
