So yes, quite certainly you can be above a pads ideal operating temp, but not so much that you're melting the the material off.
So if you took one of those pads, and continued to operate them above their temperature range, and just pushed the brake pedal harder, you don't think you'd end up destroying the pads? I suppose anything is possible, but in the real world, things generally get softer when they get hot, and soft things wear faster.
