  We review an improved statistical model of extra-galactic point-source
foregrounds first introduced in [Murray 2017], in the context of the Epoch of
Reionization. This model extends the instrumentally-convolved foreground
covariance used in inverse-covariance foreground mitigation schemes, by
considering the cosmological clustering of the sources. In this short work, we
show that over scales of $k \sim (0.6, 40.) h {\rm Mpc}^{-1}$, ignoring source
clustering is a valid approximation. This is in contrast to [Murray 2017], who
found a possibility of false detection if the clustering was ignored. The
dominant cause for this change is the introduction of a Galactic synchrotron
component which shadows the clustering of sources.
