I've noticed a similar 'puff of smoke' from A330s as the gear is selected up.
The autobrakes apply when the gear is selected up to stop the wheels before the retraction sequence starts so there are no gyroscopic forces to deal with as the undercarriage legs rotate inwards.
Used to do the brakes on/off on the MB326 before gear up during my pilot training in the RAAF for the same reason.
