Their is a typo in the code displayed in the video. The function

Curious about when you're supposed to translate "title" and when you should leave it alone? Here's the answer: You don't need to translate the 'title' attribute of an array that defines a menu item because Drupal will take care of that automatically. In fact, you shouldn't translate those as they'll end up getting double translated if you do. This is because Drupal end's up using this string of text in a number of different ways some of which don't actually need to be translated and others that do like for example when it's the title of a page or the text of a link in the menu system. The #title (and #description) property for elements in Form API array however are your responsibility to translate.
