Graeme, he is not building an output profile (in which case your
comment would apply). He is trying to match a colorimetric target on
his press, and having results that measure too blue he is forced to
increase yellow. If FWA are present, it's likely that making the
instrument measure yellower will align it better with visual
perception.
