My understanding is "they don't do usability testing" is in the context of "usability testing" being defined as hiring some usability consultants who have never designed usable software to come in and video tape random people off the street trying to accomplish canned tasks using the software. They then write the results in a report with some generic or impractical suggestions which would not actually improve usability because they are neither designers nor target users. Apple doesn't do that sort of "usability testing". However, Apple does test their products for usability.
