I saw a controlled effort to make it look like he lost control of the ball when he really didn't. For that reason I see 4 steps....travel. If you believe he lost control of the ball he did it after three steps....travel. Then he re-gained the ball before anyone or thing had touched the ball, after already taking two steps holding the ball and making a basketball move with the ball....travel.
Any way you see it, at game speed, in slow mo, whatever, that's a travel.
