[Kenobi] Is ____ holding back?

When Obi Wan goes to rescue Leia and he has that cool Starkiller-esque scene, he bludgeons the first Stormtrooper like three times with his lightsaber like it’s some kind of blunt weapon. Is he not swinging hard enough to cut through the armour? Is he putting his lightsaber on a lower power setting? If so, why?

We've seen times when a light saber is difficult to use if the wilder is not one with it. Din wielding the Darksaber is another good example of this.

Obi-Wan has lost faith in his abilities, and more importantly, lost faith in the Force. The blade reacts to that, making it harder to wield. So there's no force (slight pun intended) behind the blows. They score, but it's not going to cut off limbs.
