Considering that Naruto has dealt with physical aspects and spiritual aspects (mostly in the form of Yang chakra and Yin chakra) for a long time, could it be that it's meant in the sense that the Sword of Kusanagi is focused on physical attributes and the Totsuka Blade is focused on spiritual attributes? I like the theories presented by others so far; I just wanted to add my two cents and see what everyone thinks.
