The theory predicts that X is inaccessible for interaction, but indirectly manageable through statistical interference. Indeed, that is how we can predict where the particle will land in the two slits experiments. That is why we need to distinguish pure state and mixture. The many superposition are not accessible once we belong to a term, but there is no reason (except some dualist non-mechanist theory of mind ) to make them disappear in that case.
