The reason for this design choice is so that the two lights taken together is supposed to look like the British flag, the Union Jack.
If the idea was to playfully invoke the image of the Union Jack, it failed as far as I was concerned because I did not recognize the two lights as the flag until it was pointed out to me. A representative from the company said that he did not think other drivers would be confused as to the direction in which the car was planning to move. That may well be so but it does seem to be an unnecessary distraction. Switching the two designs would be simple and make a lot more sense.
