Is this traveling?

Hey guys, I have a question. I know this move as the "head fake and step under" I will do my best to explain it.
Say a player gets the ball on the left block, and he turns to his right to face the defender, establishing his right foot as his pivot foot. He gives a quick head/ball fake and when the defender goes for the ball he takes one step under the defender with his left foot. Now when he takes this step he picks up his pivot foot (right foot) and jumps off of his left leg for a shot.
Is this traveling?
I have seen this done many times, and have used it many times. What's your take on this?
Thanks
