All the `B(Cb, Cs)` formulas in [C&B Level 2](https://drafts.fxtf.org/compositing-2/#blending) describe the pure blend step. The compositing that happens afterwards to compute the final composited color, `Cr`, uses B(Cb, Cs) as one of its inputs and is mentioned in the introductory section of the Blending chapter:

Cr = (1 - αb) x Cs + αb x B(Cb, Cs)
