No, you can go to your back with sacrifice throws, its about who is in control at the time of the throw. Tomoe Nage is one of the most common sacrifice throws in Judo (which goes across your back).
However there are other pieces that says its a hybrid set of rules, 100% sure its not standard judo rules. Regardless it doesn't take away from Decatur's performance.
