My theory is that Amon, Noatak having been a Waterbender and Bloodbender, probably knew a decent amount about the energy pathways in the human body to begin with, and from this Amon (who was a Waterbending prodigy, after all) eventually figured out how to use bloodbending to create bloodclotts around the Light Chakra in the forehead to prevent energy from flowing into it, thus imposing the illusion of severance from one's element and preventing the telekinetic control of one's element thereby. That would explain the placement of  Amon's hands when he takes away their bending, anyways.
