I looked further:

        if (SCOPE_TEST(SCOPE_PRIVATE) || node->nd_mid == init) {
        noex = NOEX_PRIVATE;
        }
        else if (SCOPE_TEST(SCOPE_PROTECTED)) {
        noex = NOEX_PROTECTED;
        }
        else {
        noex = NOEX_PUBLIC;
        }

UP TO HERE -- OK
        if (body && origin == ruby_class && body->nd_body == 0) {
        noex |= NOEX_NOSUPER;
        }

What does NOEX_NOSUPER Represent?

        defn = copy_node_scope(node->nd_defn, ruby_cref);
        rb_add_method(ruby_class, node->nd_mid, defn, noex);

HERE I get confused AGAIN -- We have already ADDED THE METHOD
and now WE ADD a second one?    What is  SCOPE_MODFUNC represent?

        if (scope_vmode == SCOPE_MODFUNC) {
        rb_add_method(rb_singleton_class(ruby_class),
                  node->nd_mid, defn, NOEX_PUBLIC);
        }
