I can't give you a /good/ reason, necessarily, but...

As I understand it, spot lamps throw a long-distance, focused point beam.
Fog lamps throw a low, wide beam focused closer to the vehicle.   It's
possible that in non-foggy conditions, someone like a rally car may want
the benefits of both of those types of illumination at the same time.  I
don't know whya single switch would be preferable to individual controls,
but maybe it saves space for stopwatches?
