They are not equivalent, because the worlds depends not only on the
system (the electrons), but also on the measuring apparatus and the
environment. For ideal systems like this, we can probably ignore the
environment though. Since the magnets have different orientations, the
worlds are different, and correspond to different sets of branches in
each world.
