Just because it hasn't happened to you, doesn't mean it doesn't happen.
It is a very common error people make in putting a dial indicator on a rotor and assuming the errant reading indicates a "warped rotor". What you are seeing is uneven rotor wear due to worn or damaged pads, not warpage. There are literally dozens of sources available online which discuss the myth of the "warped rotor". Please note, I am not saying it is impossible for a rotor to warp, just unlikely in the extreme.

A much more likely cause would be failed thrust arm bushings, as posted by others.
