Q:

What's the meaning of the ending of "Another Earth"?

At the end of the movie "Another Earth", Rhoda encounters herself in front of her house's garage. It's very obvious that almost the same events did occur on Earth 2 and her mirror did travel to Earth 1 which both suggests that the synchronicity didn't break 4 years ago when Earth 2 was discovered but it also suggests that the synchronicity is broken because Rhoda from Earth 1 didn't travel to Earth 2.
How should we interpret it?

A:

No, It's the opposite and it's easy to see the difference between "Rhoda 1" and  "Rhoda 2"s clothes and overall look which suggests that the synchronicity did break and "Rhoda 2" didn't kill John's family, didn't go to the prison but rather went to MIT and had a successful life.
