PVS-Studio warning V525 for win32-framework

BOOL CMainFrame::OnCommand(WPARAM wParam, LPARAM lParam)
{
  ...
  case IDM_FILE_OPEN:
    // Refer to the tutorial for an example of OnFileOpen
    OnFileOpen();
    return TRUE;
  case IDM_FILE_SAVE:
    // Refer to the tutorial for an example of OnFileSave
    OnFileSave();
    return TRUE;
  case IDM_FILE_SAVEAS:
    // Refer to the tutorial for an example of OnFileSaveAs
    OnFileSave();
    return TRUE;
  ...
}

Most likely this is what should be written here: case IDM_FILE_SAVEAS: OnFileSaveAs() ....
