I'm not 100% sure but I think it's because if the axle is bent it can induce lateral forces in the fork legs causing them to bind slightly. Another possibility is that it loads the wheel bearings causing a little bit of extra friction with every revolution. As someone mentioned previously, it's often looseness and/or binding in some part of the suspension that causes a wobble.
I do recall reading somewhere that bent axles are supposed to cause wobbles (they're right up there with loose head bearings and worn swingarm bushings). When you reinstall a front axle I believe you're supposed to rotate it in the fork legs and ensure there's no binding before you tighten up the pinch bolt.
