In this aspect being able to mount and have the horse move forward with no resistance. Tern very loosely used as that is not truly broke. But since nothing changed after and all progress went one step in front of the other with no resistance ( until he got to be about 5) then in a real sense he was.
He could drive, do turns on the forehand, turns on the haunches, leg yields, back up, half pass all in a decent body frame before he was ever mounted the sitting on him was just a formality.
