Its a review job, isn't it. Glass is obviously going to have some elasticity in the central area, but near to any fixing it will be more ridged, it could be possible you were totally unlucky that a small object has hit the same area again, but for sure when stripping it out of the frame i would be thoroughly inspecting that location of the frame, the teeniest piece of debree (glass) if left within the frame could shatter the new Screen.
