Off base—in MWI, “observer” means “thing that gets entangled with the system.” Before it gets entangled with the system, the system is really truly not observed. Before being observed, things really are indeterminate from the perspective of the observer (see Bell’s inequality), and so representing them as if they were determined doesn’t work.
