I think videos like that are good and bad. They are good for people to see what high level riding can look like and give some indication of the riding/teaching standards to instructors.
However, they also hurt because then you think things like "that's what a dynamic carved turn should look like" and try to mimic it. There are basic elements to anything we do on a snowboard that have to be there, but to what degree and how the rider wants to make them happen is what creates style. That is something that I know AASI-E wants to preserve. Otherwise, snowboarding turns into skiing and people are failing exams because they don't have the right form.
However, I do agree that AASI could use a better video presence on the web.
