Certain vehicles, ie. Volvo, Jaguar, some Audis have 2 rear fog lights.
Mostly this is because of the switch from left hand drive to right hand drive in certain countries. By having 2 rear foglights, this will ensure that the foglight is always on the correct side of the lane with traffic.
Most people in NA that I have spoken to about my rear fog, think one of my brake lights are burnt out. I have hooked up both on my GTI. The more lights at the rear in the fog the less likely the car behind me will end up in my backseat
The rear foglight is used mainly in Europe where fog is a large issue. Like the other member pointed out, its only one light to not look like you are braking but allowing you to "stand" out in the back and keep the other drivers alert.

The other reason it's only on the left is because in Germany, you are not supposed to drive in the left lane - you only use it to pass. You are only allowed to pass on the left on the autobahn so that's where it makes the most sense to put the light.
Here's my confusion. Why does Audi's A6 have dual rear foglights on their car using your reasoning? I've only seen that on an Audi and I can't tell you how man many times people tell me that I have a blown brake light. I even stopped using it for a while.

Volvos are also the same way (dual rear fog lights) Perhaps they heard enough people complaining that it looked lame and changed it to dual. I've wired mine to light up on both sides cause I didn't like the way it looked, either. They're very bright though so I mainly just use them in combination with my brake lights when someone's tailgating me. LOL
