Since backreaction is evaluated from the global distribution of matter inhomogeneities, the event horizon demarcates the spatial regions which are causally connected to us, and hence impact the evolution of our part of the Universe.
Effect of cosmic backreaction on the future evolution of an accelerating universe
In this manner we are able to demarcate the regions in parameter space for which the effect of backreaction from inhomogeneities causes the global acceleration to first slow down, and then ensures the onset of another future decelerating era.
