You have to use it in tandem with the juke performed with the right stick. I've had the most luck doing a double juke by using the right stick to juke to the outside and then changing direction immediately with the left stick to the inside. If you try and double juke with the right stick you'll just kinda shuffle your feet back and forth without really every changing direction. Being able to control the left stick instead of just jamming it as far as you can in different directions is more important this year than ever. Just remember that the right stick controls the moves but the left stick is what ultimately controls the direction you move.
