That's correct.

Re-read what the Old Mechanic said;

If you get more air mass in the cylinder with a lower percentage of fuel then you can get the same power with less fuel.
Same power with less fuel.... lol

I think he is getting into the dynamics of air mass and consumption per revolution in trying to explain same power with less fuel, but it would good if he could elaborate on it much more, otherwise it makes little sense. An example always helps..
