How to Cross over turn on rollerblades

In this video, a skater demonstrates and explains how to make a cross over turn on roller blades.The cross over is similar to a turn, but it is done much faster and it increases your speed while turning because you can push off. The skater demonstrates the turn around a cone. He skates normally towards it on the right side. When he has reached the cone, he lifts his right foot and crosses it over the left foot in front while starting to turn. He then lifts his left foot and positions it normally while turning some more. He turned 180 degrees around the cone and kept good speed.
