The center one throttles back to 58% a few seconds after liftoff. When the outer two run out, the center CBC (which still has fuel left) goes to full power and the outer two separate. The center CBC runs for a little bit longer until 1-2 sep.If you go back and watch the video of the last D-IVH launch, you can actually see the center engine throttle down if you look closely. The flame gets a little smaller compared to the outers.
