A deja-vu in the Matrix is a sign of something being changed only. Since the deja-vu (black cat) in M1 was NOT a reload of the Matrix, a deja-vu does not equal Reloaded.
The One is NOT returned anywhere. The anomaly is needed to Reload the Matrix. Since Neo glows when he’s transported off at the end of Revolutions, and all that glows seen though “Those” eyes are connected to the Source, the only thing that could make Neo glow would be the anomaly. Hence the anomaly was NOT retrieved from Neo.
Neo was the sixth One. Not the first, second, third…fifth One. Nor could he be the seventh One, as the system now frees the people who CREATE the anomaly in the first place.
This has happened FIVE times. So you can speak of a Matrix 3.0 (First One), Matrix 3.1 (Second One)… Matrix 3.5 (Sixth One, Neo). Each Reload has run though the 20th century, while Zion has been rebuild and restored by rebels and freed minds who knew NOTHING about the truth.
We are still in Matrix 3.5 as the matrix was not Reloaded. Neo retained the anomaly. There can be no other anomaly.
