In the original timeline, the Particle Accelerator was successfully launched, so it didn't give Barry his powers, he was chosen by the Speed Force.

I would say future Barry saw Barry, it's kinda a simple as that.

The newspaper was from the future, so anything altered in the altered timeline would change the future.
