It was a "retcon". When the key aspects of the 8800 architecture (which
became the 432) were developed, HOLWG hadn't even yet narrowed the
competition from four languages down to two.
It's more a matter that when the Green proposal was chosen in mid-1979,
it happened to be a moderately good fit for the 432 architecture. Since
