It is entirely possible that they suffered a bird strike or other mechanical problem causing their approach to become unstabilized at a critical moment. They were too low to recover once the left wing dropped.

Monday morning armchair quarterback debrief- The cockpit alarms were probably screaming a stall warning. If they had gone to full power and pushed over the nose to stabilize the aircraft and go around this might have been avoided. It was the only trick left in the bag in their situation.

My understanding is that what is most intuitive, is often the opposite of what needs to happen, as you explain. Trying to pull out of it, makes the situation worse. I think the solution is often counter-intuitive and to go in the direction that seems like it could make it worse. Obviously, there's a lot more to it than that.
