Well you're not actually facing the ground the entire time in a cork, just the first rotation as you set, then you see the sky, then the ground again... and so on and so forth till you land. A switch cork starts with you seeing the sky as you lay on your back, then you see the ground. If you're only doing a sw cork 3 then yes you would not be facing down. Henriks one in the education of style was probably the best one I've seen.
