>From there:

   The difficulty was that when an inner recursion occurred, the value of
   car[x] wanted was the outer value, but the inner value was actually
   used. In modern terminology, lexical scoping was wanted, and dynamic
   scoping was obtained.
   I must confess that I regarded this difficulty as just a bug and
   expressed confidence that Steve Russell would soon fix it.

So it seems I was more or less right -- the semantics they
wanted was lexical scoping, effectively, even if they didn't
explicitly think about it.
