How to do Mark Suciu's “VERSO” ender in Skater XL

Low pop: Start by holding L trigger just before the pop. Flick the heelflip early and more sideways than vertical. Just after catching, turn the nollie heel upwards slightly by inverting the sticks (L @ 11 o'clock + R @ 2 o'clock), then let go of the L trigger, grind, then press in L3 and rotate the sticks in opposite direction (outward and down 7 + 5 o'clock) to revert/frontside 180 out, while also leaning using R trigger.

High pop: Delete your game.
