Isn't there a speedbrake to slow the plane down say from 1500ft-500ft AGL? Then continue short finals at the approach speeds, even with one engine at 74% N1 and the other at sub-idle, the approach speed would not have crept up to 230kts. It might have been a " hurried " approach but the crew have the tools available to slow down. Like someone mentioned somewhere else, difficult questions gonna be asked unless CX has the investigators in their pocket.
