This is an example of a legal move. A player is allowed to take two steps after their gather step on a spin move at the end of a dribble.

In this example, Blue 13 starts a reverse spin move at the end of a dribble, establishing his left foot as his gather step. He then takes two further steps as he completes his spin move before shooting the ball. This is a legal move by Blue 13 and not a travelling violation.
