This kind of notation mix-up was common here, long before UNOCF was introduced.

I remember being confused about this myself, trying to figure out how ψ₀(Ω_w) can be the limit of ψ₀(ψ₁(ψ₂(ψ₃(...)))). I asked the people here about this, and got misleading and confusing answers.

It took me months to realize that the paradox stems from the simple fact that these two expressions are written in different notations.
