The idea is that if the gun is dropped on the rear of the slide, the heavier trigger will want to travel rearward, thereby causing the gun to go off. The extremely lightweight "safety", that is kept engaged by spring tension, won't have enough mass to be forced back by the kinetic energy, and will stay in the engaged position, keeping the trigger from moving rearward.
I tried explaining that last time and this is what happened in the thread.
