Gee, Bose-x, d'ya think that maybe those things "all of which are taught..." might have something in common? MAYBE, it would be important for a pilot to understand WHY doing all of that stuff TOGETHER is likely to get him killed. Furthermore, it helps to drive home the point that the condition of flight in question can be achieved in a number of ways, but that the recovery procedure is generally the same. (And NOT as has been suggested earlier, intuitive)
