Also, as Freaky nose is falling backward, it is clear he still has both arms.

The lightsaber is already swung, so Obi Wan could n't have cut off Walrus Guy's arm. This is simply a giant mistake. If there is to be a corrected version of this scene, it needs to show Freaky nose falling backward with a smoldering shoulder and show a severed humanoid arm and hand, in a tan shirt.

Adywan's "correction" was fine. The arm is clearly severed about mid-way. The still you linked to doesn't show what's going on around Evazan's elbow.
