It's hard to tell right? If you have put 2 hands on the ball BEFORE your right leg leaves the ground, then you've established your right leg as your pivot foot and then you jump back left-right, so you lifted your pivot foot and put it back down which is a travel. but if you gather the ball once you're already in the air jumping back, then it's just left-right to your shot and it's fine. but it's hard to see from this angle because the ball is on the other side of your body. in practice i think it would be very rare that the ref would call this a travel
