Possibly you're mixing up the Etihad A340 and the Saudi 747?
A340 in TLS was doing high power with no chocks. No untoward CB playing. There was a customer rep on board, but the Airbus test guy was in charge.
The Saudi 747 in KL was being taxied with 1 and 4 started but the brakes run off 2&3's hydraulics.
