This is a by product of the escape manoeuvres, not a reason for it to remain down. The gear is left down (no change to config) for one reason only - the performance of the aircraft. It is not left down in case of ground contact, rather it is left down to avoid ground contact (by not increasing drag as the doors open.)
NP on the 787 leaves the A/T engaged at all times. A gotcha is that should the main gear contact the ground, the A/T drops out. No idea if the TOGA switches were pressed before or after touch down in this case? Also, if WINDSHEAR is detected the AFDS function is altered. I believe this is common to the 777 and was a factor in the EK accident a while back in which TOGA was presumably pressed but the T/L didn’t advance as the aircraft had touched down and the crew rotated and residual energy started a climb which was short lived as there was no / little thrust.
Happy to be corrected on any / all of the above.
