Text: It is well known that the spin axis of a particle will be found to be oriented in whatever direction the experiment is designed to detect it in. Since the electron is restrained longitudinally but free laterally, it is "designed" to detect lateral spin axis orientations. Thus the orientation of the detecting electron's spin axis is constrained to the lateral plane. Its precession axis this is also constrained to the lateral plane.
