Which is what I picked up from the discussion. Maybe obvious in retrospect, but it does mean that if you say, "6 directions, 8 directions, whatever" you really don't know what you're talking about.
What is funny is despite both terms referencing different things entirely, they both represent a bias towards the artificial delineation of the body.
