No,
The hydro doesn't take any more "horsepower" to run it. It's just that people don't use 'em to their max effeciency due to their built-in infinite variable speed design.
If you were to run that ratio control at the blue line, both servos are at a ratio of 1:1 and equal to a gear drive.
Only trouble is, the only other option you have for increasing or decreasing speed is that throttle. That's why folks find it easier to just adjust speed with the transmission control.
Move the lever back from the blue and you're losing efficency because of the increased power ratio. Move the lever ahead of the blue and you're going into an "overdriven" ratio, but you also lose torque.
