As we have now seen there are two Lockes. One inhabited by Esau and one inhabited by poor old dead John Locke.
The other 'living dead' that we have seen - Alex, Christian, Horace may have also been Esau inhabiting the dead.
We have also seen that characters can literally watch themselves if the time line is fractured.
Both of these phenomenon prove that it is possible for two versions of the same person to exist at the same time. This is what the final series is about resolving.
Daniel suggested that exploding jughead near the hatch will reset the timelines. Jack certainly believes that with the explosion there will be a chance that the flight does arrive in LA.
My theory is that the explosion does allow for the flight to complete its journey to LA however it doesn't mean that the Losties disappear from their parallel world.
So while the flight touches down in LA the Losties are still left on the island.
