Basically it's just a 2 speed transmission. An enormously over complex 2 speed transmission. I guess he wants painfully slow speeds and high upper speeds. To each their own. I commend him on a unique implementation but he's taking up tons of space for it. I find the 3:1 good compromise as the stock HL gear is too fast/weak and the 4:1's and 6:1's I have made, while more realistic in scale speed are painfully slow to pay with.
