Why similar url requests are not accepted in yii1?

Question

Yii

Good afternoon, there is such a problem,
2 similar controllers in the client part: ServicesController , PagesController
For some reason, I get into the ServicesController actions without problems, but I don’t get into the PagesController actions (
domen/pages/1
Error 404
Unable to process the "pages/view" request.
domain/pages/update/1
Error 404
Unable to process the request "pages/update"
In theory, the rules for them are the same and are written in config/main.php

'<action:(login|logout|registration)>'                      =>  'users/<action>',
        '<action:(contact)>'                                        =>  'site/<action>',
        '<controller:\w+>/<id:\d+>'                                 =>  '<controller>/view',
        '<controller:\w+>/<action:\w+>/<id:\d+>'                    =>  '<controller>/<action>',
        '<controller:\w+>/<action:\w+>'                             =>  '<controller>/<action>',
        /** Менеджер */
        '<module:smanager>'                                          =>   '<module>/services/index',
        '<module:smanager>/<controller:\w+>/<id:\d+>'                =>   '<module>/<controller>/view',
        '<module:smanager>/<controller:\w+>'                         =>   '<module>/<controller>/index',
        '<module:smanager>/<controller:\w+>/<action:\w+>/<id:\d+>'   =>   '<module>/<controller>/<action>',
        '<module:smanager>/<controller:\w+>/<action:\w+>'            =>   '<module>/<controller>/<action>',

Controllers themselves have a standard set of actions. Tried changing the file and class name of PagesController to XyzController and accessing:
domain/xyz
Error 404
Unable to process request 'xyz'.
PagesController :

...
public function actionIndex() {
    $model = Pages::model()->findByPk(1);
    $this->render('index', [
      'model'	=>	$model
    ]);
  }
...

Though domain/services fulfills. Why can this be so?
