Did you or the mechanic measure the rotors for warp? Or was
it based on pedal feel?  My two thoughts on this:

1) When you are traveling on the highway and come to a sudden
    stop, the rotors heat up.  If you keep your foot on the
    brake pedal, area under the pads doesn't cool as fast as
    the exposed rotor, and that might cause the rotor to warp.

2) StopTech has a theory that the pulsing isn't from rotor warp,
    but from bits of brake pad adhering to the rotor.  When the
    pads hit that material, the coefficient of friction changes,
    causing a difference in pedal feel that feels like a warped

That would be a total of 4 cents worth of my opinion.
