Well, the point is to have enough stength for quads and jump something less exhausting in the end. The 4TEu3Lz combo is impossible because of the outside edge on the lutz. Only salchow or flip can be added, and they are cheaper. Besides, GOE points in jump combos are based on a more expensive jump regadless of their order.
My bad I misunderstood some of the commentary.
I still believe there is no incentive to show a 4-4 if you can achieve the same BV with easier combinations.
