  These differences that show up in the portrayal of Figure 6 are all non-invariant differences. For the right hand distribution, the galaxy does veer to the right in the figure, but at the same time, distances between events get stretched as well, just as they get stretched in the various map projections shown in the supplement,  Visualizing Leibniz Equivalence Through Map Projections.  So the galaxy always remains at the spatial midpoint of the galaxies on either side; it just doesn’t look like it is at the spatial midpoint from the way the figure is drawn.
