As stated the lockbar is all the way to the presentation side, no room for wear. The very next thing that is possible is to experience the lock rock wiggling. Being a frame lock and not a liner lock (there is a difference) both lock styles can have similar problems. I have an old SnG with all kinds of lock rock, and I have not even put that knife though any sort of hard use. I have not bothered to send it in because I'd imagine it would probably come back with a giant stop pin cover rendering the knife lopsided looking. A while back fans claimed that Strider had improved their lock geometry reducing the instances of this lock rock, yet it is still not as much of an improvement as it should be for the money these things cost.
I would imagine the same principles can be applied to a frame lock as to a liner lock. According to Emerson knives, the lock face and the locking bar/frame should NOT be parallel. My SnG has a very parallel lock face. The XM-18 knives I have do not exhibit the same movement, and based on my own experience they are a better designed and built knife. There is no lock rock in any of the ones I own and those knives have seen some extended use.
I wouldn't exactly call it self correcting, rather designed for wear over time. It is what keeps your knife functional over years of opening and closing.
