You seem to not understand the essence of zombies..
His neck can be broken, but his legs still move.
That shouldn't be true. The brain is necessary for the zombie to be able to move, and I'm not expert on broken necks, but I was under the impression that the reason a broken neck can cause paralysis (if it doesn't outright kill you) is due to it severing the connection between the brain and the rest of the body. So, if there's no connection, then the zombie shouldn't be able to move its body.
Meaning Shane didn't do the job properly, since Randel can walk.
Except he was dead. Which leads me to believe he
did do the job properly by severing the spinal cord and thus the connection between the brain and the rest of the body, which causes the person in question to die as all bodily systems shut down.
Anyway, I think Leaden Disintegration is right about the movie magic. The scene in the pharmacy in which Glenn goes after the walker attacking Maggie, he clearly severs the spinal cord by mostly decapitating the thing (if I'm remembering correctly), and yet it was still capable of moving.
