Nope, BMW vision was one rear lamp not two. Europe's vision, ECE 38, called for ONE OR TWO rear lamps, required. ECE R48 specifies that the rear fogs must be apart from the brake lights.

Obviously, two lights are better than one for visibility because your brain needs two light sources to triangulate the distance. This is also why cars have two headlights, two tail lights.
In North America, rear fogs are not required but permitted.
