I think the article confuses physical 'movement', with maneuvering, which in the context of maneuver warfare is more about adapting your strategy to both hit the enemy's critical vulnerabilities (again not just physical, we're talking media, moral, supply chains, sight, ability to discriminate between civilian an enemy, timely communication of orders, ability to concentrate force, etc), while covering your own.

Movement and physical speed is just the most basic of the possible maneuvers in this context.

The rest of it does seem pretty good/interesting though
