Is $section required on catalog.php?

In the video, Alena set $section to null in catalog.php. However, what purpose will this serve? As I understand it, we have already set the variable "cat" in the URL, so the conditional:

if ($_GET["cat"] == "books") {
    $pageTitle = "Books";
    $section = "books";
} else if ($_GET["cat"] == "movies") {
    $pageTitle = "Movies";
    $section = "movies";
} else if ($_GET["cat"] == "music") {
    $pageTitle = "Music";
    $section = "music";
}

will always run. Thus, $section will always have a value in catalog.php, and the header is included after the conditional.
