In the ISO 94 document the concept of nest-sys is indeed needed.

Unavoidable really.  Nesting aka subroutine call - the process of
calling a function and when it completes, returning to the caller -
is a basic computing concept.  In forth 'nest-sys' represents the
information necessary to facilitate that return.  It should not be
confused with invoking a function i.e. 'xt' EXECUTE.
