View cache documentation issue

Hi, at the end of the section "caching-view-fragments" of this page of the doc https://docs.phalcon.io/en/latest/reference/views.html#caching-view-fragments

the example (DownloadController::indexAction) checks if 'downloads' key exists, and if exists it gets the data from the model: should'n this code run if the cache entry does not exist (using the NOT operator)?

if (!$this->view->getCache()->exists('downloads')) {
    ...
}

Cheers
