RRR is correct. Without hydraulic power to sys #1 & #4 you have no brakes and no NLG & BLG steering, risking tyre damage. It also allows the control check to be carried out at a relatively quiet time during departure.
The procedure is #4, wait for LPWL out, #1, wait for LPWL out then #2 and #3. Waiting after #4 and #1 prevents fluid transfer by ensuring the brake shuttle valves are in the normal positions.
Unless the ground crew is abnormally tall, there's little threat from live flight controls.
