In the original timeline there would have been no reason to activate the magnetic field disruptors since the Reach just took over the Earth.

The juxtaposition of Neutron's defeat in the present and his reaction in the future just means Impulse's intial mission of stopping Neutron from killing Flash didn't work. Otherwise, "Bloodlines" would be the series finale, as there's no reason to continue a narrative we know ends with utter defeat.
