That is a possible sequence of events. Chop the thrust, float due to the high speed. Bring the A/C down on the ground with TLs at idle, engines hit the ground, bounce. As the crippled craft is settling down for a second, full touch-down, set TOGA realizing what just happened. The thrust comes back rather quick, but inertia and drag refuse to give up. Kinetically, nothing changes for the next 10 seconds, hence the two more scrapes.
