Actually, after looking a the video, we know that only 2% of brake wear is during the taxi-in because the brakes are hot. Therefore, while you are correct in stating that reduced brake events reduce brake wear, the brake wear is almost down to zero on the taxi-in. As stated in the video, approximately 20% of wear is during the landing(on average of course). And the most interesting part is that almost 80% of brake wear is during the so-called cold taxi when taxiing for takeoff.
