An expendable vehicle should be inherently more efficient in launching frequency than a reusable one. The reusable one is fundamentally limited by the number of reusable vehicles you have on hand and the time it takes to turn each around. The expendable one is only limited by the speed of your manufacturing. So, since SpaceX is moving to a reusable vehicle, this graph could easily change slope in the future.
