$router = ... 
    
$router->addGroup('/api', static function (RouteCollectorInterface $r) {
    $r->addRoute(Route::get('/comments'));
    $r->addGroup('/posts', static function (RouteCollectorInterface $r) {
        $r->addRoute(Route::get('/list'));
    });
    $r->addGroup('/comments', static function (RouteCollectorInterface $r) {
        $r->addRoute(Route::get('/list'));
    });
});

the loop stops at the first group found, and the remaining groups and routers are ignored
and when you try to go to the url api/comments/list returns 404
