If you cut the binding on the straight of grain, that means that you have a single long thread running across the crease of the binding. Since many children like to drag their quilts around everywhere, more stress is typically put on the binding than with a standard adult bed quilt. With that stress, a thread can snap. With SOG, that snapped thread runs the length of the binding and will unravel to leave a long gap. Once that space is there, it puts additional pressure on the other lengthwise threads & eventually other threads start to snap & unravel as well.
With bias, there aren't any long runs of a single thread anywhere on the binding. In addition, bias has more give to help it stretch and relax a bit before snapping. But even if you were to have one thread snap on the bias, it would have a much smaller impact on the remaining threads since they are running equally 2 directions & not primarily straight along the edge of the binding.
