You're confusing a few concepts here into one big concept.
What he's saying is right, a warmed up engine is more efficient, and engines have operating temperatures they're designed for, and use more fuel until they reach that temperature. Lowering the temperature the engine is trying to run at may put it out of balance, and reduce efficiency.
What you're thinking of is the temperature of intake air. It's a common misconception that colder air is better always. Cooler air is denser, and thus, requires more gas to achieve the correct mixture. Where people get tripped up is that since the air is denser, and more gas is injected, you get more power. You're not getting more power from the air, you're getting more power because you're injecting more gas in to offset the extra air.
Truthfully, a hot air intake is better for fuel economy, as hot air is less dense, and thus less gas is injected for combustion. Less gas injected = higher fuel economy.
