A vertical Stern-Gerlach spin measurement is a z-spin measurement. The Born rule gives
p(z+∣ψ+​)=p(z+∣ψ−​)=p(z−∣ψ+​)=p(z−∣ψ−​)=21​.​
(1)
Thus this measurement cannot distinguish the two preparations, even by repeating the same measurement on many identically prepared copies: it discards their relative-phase difference in this basis.
