Both perspectives are accurate.

Odysseys has a very relevent point with regard to a featured musician or signature sound, which, unfortunately doesn't seem to exist much anymore. Please, don't misconstrue this, I agree with you here. I think this approach seems to work best with very few like instruments.

I agree 100% with PTUser's guitar and bass relationship, ecspecially when you begin stacking instruments like these that tend to occupy lots of real estate. I don't think that he intended for this to be considered an exclusive technique. Just a different approach.
