Where did you see the info that they won't spawn on pre-hardmode hallow? The article is pretty clear to me. They spawn on non-hallowed blocks while you are standing in a hallowed biome, pretty much just hallowed blocks until it turns into a biome then it needs normal non-hallow blocks on top... So it works good if a snow biome was hallowed since snow blocks cant be infected.
