Specular formulas simulate lighting coming with a particular polarity pattern while Diffuse lighting simulate lighting coming with polarization patterns on a different axis.

When a light wave (polarised or not) hits a surface, it's reflected and refracted. Specular simulates the reflected parts, and Diffuse simulates the refracted parts.

Light that's polarised in different ways is still partially reflected and partially refracted (so: requires both diffuse and specular formulas).
