Exactly!
A very simple scenario based on some rough 2-cycle numbers: Let's say a Yamaha KT100 produces peak torque at 10,000rpm. It produces peak horsepower at 11,500rpm. RPM goes UP more than torque goes DOWN, or peak horsepower would not be happening at a higher rpm than peak torque! It really is that simple.
As you say, if we gear both scenarios to the same axle rpm, more horsepower at the crank produces more horsepower AND torque at the axle (since axle rpm is the same).
