I don't think the other world the second Lucy says she came from is like an "Edolas" counterpart world. Maybe more like since the time stream is going to change she will only exist in other time streams. Her saying that made me think of how Ultear references other time streams that her orbs represented. Since the time she came from will no longer be the true one (if the plan works well enough), Lucy may be able to live in the future.
