Using 5.3 as a reference (probably the same or similar in earlier
versions), the vend::Util::vendUrl() subroutine has some code that
looks like this:

        for(@scratches) {
                next if defined $opt->{$_};
                next unless defined $::Scratch->{"mv_$_"};
                $skip{$_} = 1;
                $opt->{$_} = $::Scratch->{"mv_$_"};
        }

The "no_count" keyword is in the @scratches array, defined elsewhere
in the module.  The above code will set $opt->{no_count} to equal
the value of $::Scratch->{mv_no_count} which, in turn, will be
influenced by the ScratchDefault mv_no_count (if set).

Later in the subroutine, we see this:

        $ct = ++$Vend::Session->{pageCount}
                unless $opt->{no_count};

        if($opt->{no_session}) {
                undef $id;
                undef $ct;
        }

If $ct survives the "no_session" check, it will be appended to the
generated URI parameters as follows:

        push @parms, "$::VN->{mv_pc}=$ct"                       if $ct;

I hope that explains things.
