I'm not sure I agree, but let me do some figuring and get back to you...
After "geeking" around a bit in excel, I determined that I needed more information to make a good comparison. If I had a hp & torque curve for a 22RE I could compare the gearing combinations at different speeds to see where the engine was at.

I just realized that if you changed to differential gears from 5.29 to 4.10 you would be decreasing torque to the ground by 29%, but if you shift into low you're actually increasing the torque to the ground by 228%.
Assuming 100 lb-ft of engine torque, the comparison would be the following for 4th gear:
1 x 1 x 5.29 = 529 lb-ft
1 x 2.28 x 4.10 = 934.8 lb-ft (76% increase in torque, but speed is limited due to gearing reduction)
It would be fun to compare the various gearing combinations and verify available torque at matching speeds.
