Because they say in 2046 that Sarah never came back and how in the futre where the kid is from say Sidney took over because Ray never came back, that means they never returned to 2016. So that means also that this whole show eventually is going to end with everyone dead or in the Time Vanishing Point. Not really, any time the go to any point beyond 2016 it is basically an alternate future where they never returned because.. well... they time traveled to that point.

I think that is the explanation they are going for, we don't know what time travel rules they are going by yet.
