bagginsbill will have a fully correct and educated answer, but i think diffuse in the Poser root node is diffuse texture times diffuse value times the internal diffuse shader.
edited to add: even with textures, i still find setting the values increases realism. because the effect happens regardless of the color of the object. a highly diffuse white plastic and a highly reflective white plastic would still be on either ends of the extreme.
