The one having "close to 1/2 of the coma of a standard Newtonian"?
Seems the one who wrote that was comparing the final system coma coefficient
to that of the spherical primary, not realizing that coma coefficient of the 
latter
is reduced vs. parabolic primary due to effective stop placed at the 
corrector
location. Mak-Newt normally has only ~30% of the coma of a comparable
Newtonian.
