I added token providing functions to the module

I'm using the nodewords_bypath module. The problem with it is that it overrides the meta tags that are entered for specific nodes. To fix this I've added some token providing modules to nodewords.module. The code is below. Will this create any problems? Is it useful?

Thanks,
Moses

/**
 * Implementation of hook_token_values().
 */
function nodewords_token_values($type, $object = NULL, $options = array()) {
  if($type = 'node'){
    $tokens['meta-keywords']      = $object->nodewords['keywords'];
    $tokens['meta-description']      = $object->nodewords['description'];
    return $tokens;
  }
  else{
    return;
  }
}

/**
 * Implementation of hook_token_list() for Pathauto specific tokens
 */
function nodewords_token_list($type = 'all') {

  $tokens = array();
  if (module_exists('nodewords_bypath')) {
    if ($type == 'node' || $type == 'all') {
      $tokens['node']['meta-keywords'] = t("The meta keywords");
      $tokens['node']['meta-description'] = t("The meta description");
    }
  }
  return $tokens;
