Hello Mario, I'm not sure I understand your question.
There are certain situations where before the throw uke has a split second choice that he can do a roll or a high breakfall but he does the breakfall anyway. then there are some situations where nage is in full control and uke doesn't have a choice. In these situations, as the other poster said (probably because of your intensive ukemi training) the body goes on autopilot. You're OK after the fall, you meet the ground and sometimes, you don't know what had just happened. You just remember being flipped. You just let go and trust your experience will save you from injury.
