That's good, but he's right. Any OEM brake pad formula (Highest-end cars aside) has a propensity for this because they're pretty much universally 'Material Transfer' pads.

The only cars I've owned that this has happened have been ATX cars where you HAVE to apply brake force much more often than in an MTX.

The worst part is, it can be hidden from you in a used car by having the rotors turned. As soon as you wear them in a little it'll come right back, because it causes a chemical change in the rotor material that goes deeper than the surface. You have to take of a couple tenths of the entire rotor surface to get below it (which may result in taking off several tenths on the high spots), which almost never happens. They just even it up and call it a day.
