There seems to be some variation depending on the model-year in question.
The later models use the upper lights (on the tailgate) as side lights while the lower ones are used for brakes, as shown below. This is the opposite of my '08 model.
Also have you noticed that with the tailgate open, the brakes operate the lower set of lights, presumably as the normal ones on the tailgate are pointing upwards. It would make more sense for both sets to be used for brake lights to give maximum visibility.
