I had this conversation with an english professor and based on the study of Etymology (the study of words) "switch" is the correct term. All words have a "root" which is where it came from, and since skateboarding is what started all this shenanigans that is the root. According to him, "switch" is appropriate for any riding style that is the opposite of the normal way to ride, regardless of your feet being connected.
Your Welcome, and good luck on those switch tricks!
