OK, it's really hard top understand technical explanations in print, more so with an unfamiliar name. So I'm not exactly sure what technique you're talking about here. have you asked a senior at your dojo? Always my first question in this kind of situation. General advice for not falling over: make sure that the elbow that was used to lift his chin is over your knee at the end of the throw. If you're doing what I think you're doing, you're turning your hips too far so that your arm goes past your knee and you lose your balance. Again, this is just an idea based on what I think you meant, but I probably misunderstood you. Ask someone who can see what you're doing.
