Boomer, There are some here that may have learned Okuden(inner circle teachings), but many have not been in karate long enough to know or be exposed to what you are talking about.
If you are talking about he one at the end of empi(Shotokan Wansu), then I believe that it is a throw. From what I have found it looks like you are going to throw someone just as another attacker is trying to tackle you legs, hence the reason for the jump and turn.
I presume that this is the waza that you are talking about?
