Eh, I dunno if they are both considered Osiris.
All the Osiris specific tutorials refer to the Story editor. Both for 1 and 2.
They are both Osiris. They are "Osiris-used-for-story" and "Osiris-used-for-behaviors." You're using one language for different systems. You're making this more complex and confusing than it needs to be. Larian refers to their only scripting language as just Osiris.
