He's telling the truth puzz.

Tell your unit to charge an enemy unit that has 2 or 3 other enemy units near it.. and the targeted unit instantly reacts the moment you click.

But if you tell your unit to move right next to the enemy unit without attacking, you can literally PARK your unit right next to the enemy without them countering your move.

This is most noticable with archers. In the middle of a fight, when enemy archers are shooting at your melee unit, you take a free melee unit thats far from the melee and order it to attack the archers. The INSTANT you click on the attack order the archers switch target or change formation to face their long-away attackers. BUT if you tell this melee unit of yours to walk or even run RIGHT next to the archers, the archers never react, even when the YA is almost right on top of them.
