Well, thats true to some extent. It doesn't actually have better wear than stainless, it has better wear in terms of longevity as a protectant but not as a stand alone substance like the stainless would be. In other words when its worn away finally in the somewhat far future, compared to an untreated barrel you will probably get the same basic service for wear from the untreated stainless steel but for a shorter period of time. Its a sacrificial coating, it just happens to have a long life span.
