OK, I didn't know there was already a prototype registered for TraversalOrderBin. You learn something new every day.
Anyway, if I understand your drawing correctly, I would comment that the only put into render bins are Drawables (not transforms). So if you have your Transforms set to a depth-sort bin, but all the drawables set to a traversal-order bin.. there's no depth sorting actually taking place b/c there aren't any drawables in a depth-sort bin. Does that make any sense? I could be wrong.
