Howe refers to the true 100 yard zero as a "100 yard POA/POI zero".
In the article, he is comparing two different zeroing systems: 1) the 100 yard POA/POI and 2) the 3 inch offset; but advocating sighting them both in at 100 yards ("zeroing" them in at 100 yards in his terminology).
His preference is clearly for the 3 inch offset zero at 100 yards, based on his experience that it facilitates headshots at 100 yards (by "lollipopping" the head) and suffers from less of a dropoff at 300 yards.
Molon's point was that the presented 3 inch offset is technically a "280 yard zero" sighted in at 100 yards--and that a shooter may be better off with a zero that gives him a flatter trajectory (like a true 50 yard zero).
