Yes but the fact remains that the rendering engine is Lux.  I've seen similar slogans but all were referring to the renderer, not any other mediums.   For example, we can export from Poser to Bryce, Vue, Carrara, etc.    Nowhere are the exporters mentioned but rather the application used for the final render.   But then again, if that rocks your boat it's fine with me, just seemed a little over the top :)
