Not to mention that triangulating a suspension component would allow you to make the A arm thinner and block less air heading to the back of the car.
There is something to stop the wheel from shifting, the 'lower wishbone' that branches of the main. I am in no way an expert but the only downside I could see is that you would not be able to have control over camber as the suspension compresses, it would be a constant change in camber. With two separate wishbones you can control the camber rate as the suspension compresses. excuse the brutal diagram but this is how:

this would hold the tire from doing anything, a --- ton of stress for that member though
I am not saying it does only have a top wishbone or it does not. I do want more pictures of the rear suspension though as it looks interesting.
