This is because the typical DI system directs gas pressure immediately to the center line of the the carrier, behind the bolt. That's where the force is then directed straight back through the carrier to cycle the action. A piston kit directs the pressure up at the carrier key, which then tries to cam the carrier down at the rear.
That's the idea anyway.
