In the sense that it’s two different but similar states.
I’m pretty sure we can say it’s not actually spin now. Electrons have a charge and a magnetic field. If they are charged and spinning that world generate a magnetic field. So spin was used to describe the orientation of the field. The name for the state stuck
Sorta like linear vs. circular polarization in radio transmissions?
