That isn't quite what happened. The 1979 BCP cribbed from the 1970 Missale Romanum (the "Novus Ordo") and the Anglican Use also took some stuff from the Novus Ordo. (Some of which they were required to take for doctrinal reasons; the 1928 Episcopal liturgy isn't entirely suitable for Catholic use.)
Ah. I recognized that some parts of the "Anglican Use" had to have come from somewhere else because they certainly weren't in either the '28 or the '79, but I am perfectly happy to agree (not knowing one way or the other) that the truly clunky parts I recognize from the '79 were lifted by its tin-eared drafters from the Novus Ordo also.
