I note the following:

The first time that I saw this code a week or so ago, it took me a
minute to figure out just what was going on.  Seeing it again, I had
the same problem but this time I had some docs to fall back on. 
However, I can't help but notice that the docs describe things
differently from the code.  I'd suggest using the following which
exactly matches the description:

sub end : Global {
    my ( $self, $c ) = @_;

    $c->forward( 'MyApp::V::TT' ) 
        if ( $c->stash->{template} && !$c->res->body );
}
