My reasoning is rotors are usually made out of cast iron and the term "warp" really is a poor saying that has become the norm over time. It is very difficult to warp cast iron. The heat necessary to do so isn't something the average road going car is able to produce.
What's more likely is distortion or grooving of the surface as a result of suspension and brake rotor misalignment which means that the pad isn't sitting flush with the rotor causing uneven surface wear.
Chances are that if this problem persists despite new rotors, pads et al the problem exists with the suspension. Even pot holes will cause suspension and brake misalignment and result in brake issues as they accumulate. Has he had the suspension checked out thoroughly and/or had an alignment done in recent history?

Suspension will have 0 impact on brake components seeing as they are in fact attached to the bottom of the struts.
alignment can cause a vibration, but when you change your rotors and drive 10k with no more issue but comes back and again is remedied from rotors its very clear the issue is not the suspension. Not to mention G35's were known for this problem from day one and the easy fix was non-OE pads.
