I think part of it is that the article sounds incredibly speculative and "just so". It doesn't, in other words, appear to be researched, and it is about something (the causality of our directional associations) which would be really hard to know even if you were to stare at all the known historical facts without uncertainty about them. So if it's all conjecture, and you wipe the conjectures away, you really do have "I think it's either because shadows in the Northern hemisphere go from left to right when you're facing North, or because when you track the Sun across the sky from that hemisphere, you have to face South and then the Sun describes an arc from left to right."
