The answer must be that the technique of 'following through' is taught during the MCC/APS course.
As threat & error management continues to be instilled during this initial multi crew training, I would suggest that any provider worth its salt would "encourage" it from day one. It is always important to fail the A/T during the MCC to prove the point. They become so dependent so soon. A rapid addiction occurs.
I could go down the route and say it is good AIRMANSHIP, not to be confused with good old fashion common sense.
No doubt the THOUGHT POLICE will be on my case any time soon.
