I was using _make_phased_magseries_plot, and noticed for stars with flares (or other "ramp" like systematics) that the phase-folded ylimits would be totally off. Sigma clipping (or windowed sigma clipping) goes some way to a workaround, but if the light curve has other variability it can fail. So: the option implemented here is a simple fix that usually works, and doesn't change any of the default options.
