That's how much power the transmission would require at stall, but the output power at stall is 0 hp because the motor isn't spinning and isn't doing work.

The output power for a motor is equal to force x velocity or rotational velocity x torque. At free speed, you have a large rotational velocity but no torque, and at stall, you have lots of torque, but no rotational velocity. Halfway in between is where you'll maximize power.
