AngularJS supports 2 methods of registering controller functions - either as globally accessible functions (you can see this form in the mentioned tutorial) or as a part of a modules (that forms a kind of namespace). More info on modules can be found here: http://docs.angularjs.org/guide/module but in short one would register a controller in a module like so:

angular.module('[module name]', []).controller('PhoneListCtrl', function($scope) {

  $scope.phones = [..];

  $scope.orderProp = 'age';
});

AngularJS uses a short, global-function form of declaring controllers in many examples but while this form is good for quick samples it rather shouldn't be used in real-life applications.

In short: AngularJS makes it possible to properly encapsulate controller functions but also exposes a simpler, quick & dirty way of declaring them as global functions.
