I think the note means that the variable is defined in the file, but
has no effect when using PAM. The note names one possible workaround
to modify the super-user path when using shadow with PAM support.
ENV_SUPATH exists in /etc/login.defs but does not do or cause any
behavior.

So the note mentions a step that has not yet been performed nor is
described in detail.
