Saxophone and breathing 

This is a very interesting question and one I feel I need to think a little more deeply on, possibly another RU-vid video to express my thoughts on the process of moving actions into the subconscious. We of course breathe subconsciously to stay alive but we must breathe with more purpose when playing a wind (or brass) instrument. My initial thoughts on this wont come as a surprise or be groundbreaking in that repetition and the reinforcement of good habit is the best thing to work on. Initially the action must be conscious and have purpose but eventually the action becomes second nature and "the way you do things", just like driving a car or brushing your teeth. Thank you for your question and hope this response is useful.
