I agree you can waste a lot of energy pushing harder without gaining in an IC engine. I think the idea was specifically associated with Diesels as they are fuel controlled - more pedal, more fuel. A petrol unit the fuel delivered depends on airflow, throttle position, temp, boost (if you have a turbo) etc. If you floor it you just open the throttle wide. In a Diesel there isn't one, you just pump in more fuel.
