. On more advanced level aite will help tori less and less, until the point where tori must really take the balance of aite.
That never happens in Ch. Tissier style. I had a chance to practice with his many very high ranking students, every time I was corrected to follow famous 'code'. They simply don't accept when uke moves other way and get immediately angry. The root of theirs behavior is they don't know what to do with different reactions of attacker and how to control him in safe way.
So I lost interest to practice with this style because this ‘code' (in short or long term) doesn't allow the development of spontaneous creation of the techniques. And this is in contradiction with O sensei teaching.
