He is saying that when coasting (foot off accelerator), it is better to leave it in gear rather than idle.

The reason being at idle you're burning gas at 750rpm with cylinders firing.

Staying in gear, even though you're at say, 3000rpm, not one drop of fuel is used (or close to that). The ECU cuts the gas completely off.

When in motion, If idle RPM is @ 750, that should reduce fuel consumption as when the engine speed is @ 1K + RPM.
