Surely not...
There is a best glide speed for everything flying including a brick...And 113 KTS is far from it because it is closer to a stall and probably beyond it. B777 is not a glider but still is a machine heavier than air, on which all aerodynamics laws apply. Judging (not sentencing) the crew action bringing it almost to a stall on A/P it could have been better handled and surely more followed up by Boeing in some AD, Urgent circular or something similar...
