If you read the article carefully, you will understand that reducing the AFR, that is, enriching the mixture is only adding fuel, not air, because you don't am supercharging, so you cool the engine and as a result you will lose power sooner, because power comes from temperature and tuning is to advance the ignition timing at high revs, so that you don't get knock combustion, but because accelerating the ignition causes an increase in temperature, because the mixture burns more you have to add AFR to make the fuel cool the combustion chamber.
