Ventilation perfusion coupling means that more blood flows past functional alveoli than nonfunctional alveoli?

Yes.

Ventilation perfusion coupling means that there is a matching of ventilation and perfusion in the lungs. This means that more air flows to areas of the lungs that have more blood flow, and less air flows to areas of the lungs that have less blood flow. This matching ensures that the oxygen in the air is efficiently delivered to the blood, and that the carbon dioxide in the blood is efficiently removed.
