The 6 Plus bends more easily because the distance between the weak spot (fulcrum) and edges (lever) is greater than the 6. You are able to apply more force to the weak spot. And it will break. Simple physics of fulcrums and levers.
but the argument has been the thickness and the construction, that shouldnt matter then when the length is just 1 inch longer. the result wouldnt be that drastic...
