By my understanding, the area of single line is not the weakest point in a whoopie. It is the distorted area of the constrictor where the free end of the adjustable bury exits the constrictor. Overlapping the buries would further stress this area making it even weaker.
Again...this is my understanding, but I am fairly confident it is correct.
