Watch the Hybrid Picking: Level 2 online guitar lesson by Chris Buono from Guitar Gym: Hybrid Picking
Throughout Level 2 the Workouts you'll play through an A natural minor scale (AKA the Aeolian mode). You'll play the scale in diatonic 4ths going in what I call "basic motions" where you'll play the intervals in the same direction both ascending and descending. Much like you established in Level 1 the first pick hand attack should be a downstroke while the next attack should be a P2 acting as an upstroke so to speak. This sets up a situation where you're picking each interval pair on the outside of the adjacent string pairs in a "surrounding motion."
