fuel would tip from the higher to the lower wing tanks due to an always open high level weir, the type's anherdral added to the imbalance which had to be managed via cross feeding.
Why is that? If the aircraft was being flown accurately with the ball in the centre (whether manually or on AP), the lift and weight vectors in the turns would be perpendicular to the aircraft axis, so the fuel would behave exactly as if in straight and level flight.
