Rick is awesome, no doubt about that, but without even rising to the issue of whether "instinctive" shooters use sight picture as part of their aiming system the video does not do what you claim it does. It does not prove that people do not subconsciously use exteroceptive sight picture in conjunction with their proprioceptive sense as part of "instinctive" aiming. In fact, Rick even says that if you are shooting "instinctive" that "you are not consciously using [the arrow] as a gauge."
While it is true that you have to decide whether to focus on the target or your sight (be it an actual sight or a reference like the point of your arrow) it is just flat out wrong wrong to claim you have to focus on the arrow to use Point Offset Aiming/Point of Aim/Gap Shooting--you don't. Whether you focus on the target or the arrow/target sight reticule, is a choice.
