Maybe the engines woke up, realized they had to decelerate from 270 m/s to 0 in less than one second, and they gave it their all?Likely the engine compartment was simply trying to leave Planet Earth.
Well, it's orbital ellipse probably did have next apogee far in outer space...In Orbiter, "landing" at these ridiculous speeds sometimes makes a vessel to bounce very very far and fast into outer space....
maybe they were checking if that's a real phenomenon

On the bright side, they don't have to worry about the pumps cavitating.Generally, I don't want to be the guy who told the engine and propellant delivery system designers that they should assume g >> 270 m/s² for the hydrostatic calculations of the head pressure. There are not many easier ways to destroy a pipe.
