If Congonhas had the EMAS, the crew would've headed for it. They kept the aircraft on the runway until they turned it.
Not a factual statement, 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.
Besides, why would the crew want to consciously "turn" and exit the pavement prior to reaching the threshold, and not utilize the extra overrun pavement beyond the threshold?
