I think it's mostly a matter of ease. It's all done from touch typist
home position, with one hand. Back then there was no mouse, so they
chose the right hand, dominant on the majority of people, as that hand.
I'd guess if mice had existed universally when vi was created, the
cursor keys would have been done by the left hand so the user could
keep his or her right hand on the mouse.

I think the mnemonics were in the fingers, not in the brain.
