Redirect to default node url

Question

I have an question about drupal's redirect.

Well I implemented hook_menu for the path: "node/%node/boost".

And I set all callbacks from default node path: "node/%node".

/**
 * Implements hook_menu().
 */
function my_module_menu() {
  $items['node/%node/boost'] = array(
    'title callback' => 'node_page_title',
    'title arguments' => array(1),
    'page callback' => 'node_page_view',
    'page arguments' => array(1),
    'access callback' => 'node_access',
    'access arguments' => array('view', 1),
  );

  return $items;
}

So I would get the node from my custom URL

but I got the redirect to default node URL like "node/123".

Any idea how can I load nodes from the my custom URL?

Thanks

UPD

If I change "page callback" function to the my custom function "my_module_page_view", for example:

/**
 * Callback.
 */
function my_module_page_view($node) {
  return 'Hello Drupal!';
}

I will see the text "Hello Drupal!" on the page with URL "/node/1/boost".

But if I use the next code:

/**
 * Callback.
 */
function my_module_page_view($node) {
  return node_view($node);
}

I will get redirect from "/node/1/boost" to "/node/1"

Well It was a monkey's code in the one custom module: It implements hook_node_view() and, if the path was similar to node/1/bla-bla, it redirected users to node/1.
