RF changed the timeline by making Barry The Flash a lot earlier than he was supposed to. The stuff on the paper might no even happen. Heck even Barry messed with the timeline when he prevented the tsunami, and he might fuck it even more if he tries to safe his mom and succeeds. Nothing is really set yet.
The show has shown that if the events in the present change the timeline, it's reflected by the newspaper changing. So as of the moment they saw the paper, everything was still destined to happen as shown on it.
It could always change between now and then but nothing currently suggests it will.
