Cannot use the same variable in the inner and outer foreach loop ( $label )

Here is the offending code from s \Drupal\entity\Tests\ContentTranslationWorkflowsTest::testWorkflows

    foreach ($ops as $current_op => $label) {
      $user = $this->drupalCreateUser(array($this->getTranslatePermission(), "$current_op content translations"));
      $this->drupalLogin($user);
      $this->drupalGet($translations_path);

      foreach ($ops as $op => $label) {
        if ($op != $current_op) {
          $this->assertNoLink($label, format_string('No %op link found.', array('%op' => $label)));
        }
        else {
          $this->assertLink($label, 0, format_string('%op link found.', array('%op' => $label)));
        }
      }
    }

For only a moment it left my brain going what which $label is important here!!!

since the $label in the outer loop is unused.. I dont think it will alter the execution flow through the loops.
