Weird, I've never heard anyone teach that. Maybe they changed it only recently but heres the official "AASI" wording.
Snowboard Certification Standards 2012
National Standards: Level One, Level Two, Level Three
The successful rider will demonstrate an understanding of the Approach, Takeoff, Maneuver, Landing (A.T.M.L. TM) model, and will demonstrate the skill and confidence to use the A.T.M.L. TM model on a small terrain park jump.
Approach: Judge the necessary speed for the approach to a feature of particular size in order to land in the designated landing zone. Maintain a flat board during the in-run as well as on the ride into the takeoff zone.
Take off: Balance and stability through a smooth takeoff.
Maneuver: Balance and control of body while in flight.
Landing: Keep the feet under the torso (i.e., for a simple straight air), align to the landing zone, ride a flat board away with confidence and control.
