Glueball,
You're not too factual either, sorry.
... because when the left engine is developing reverse thrust and the right engine is developing climb thrust then there is no way the airplane can be kept in a straight line. The severe asymetric power is turning the airplane to the left; rudder authority and tiller steering control are exceeded.
Do you have data, figures, or a simulation to substantiate that?
Why would the crew want to consciously "turn" and exit the pavement prior to reaching the threshold...
IIRC there is a "Turn, turn!" on the CVR towards the end. Trying to run the aircraft off the runway and into the mud, and trying to ground-loop as a last desperate measure?
... and not utilize the extra overrun pavement beyond the threshold?
Look at the maps and photos. There is virtually none, and they knew that.
