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 
the DoD was backing it, the expectation was that Ada would become very 
popular.

The first high-level language Intel shipped to 432 customers actually 
was not Ada, but rather a Smalltalk dialect called OPL ("Object 
Programming Language"), derived from Rosetta Smalltalk.  The Rosetta 
Inc. web site apparently went away within the last year.
