To get the effect you're looking for, you'll need to duplicate the CombatStyle used by the creature (in the Misc section of the Object list in the CS), and adjust the values to suit your needs on your duplicate.
Most summons and companions will run far ahead of their "owner" to engage new targets. It's a vanilla AI "feature". If CombatStyle changes aren't enough, also consider reducing the actor's detection range or scripting the actor to only engage in combat with actors that are already in combat with the player.
