Limitation in the Drupal Menu system

The Drupal menu system API says that each path in the menu should be unique. I think it should read "must be unique".

On his blog, ragaskar talks about his own problems he had with menu items pointing to the same path.

If I want to have multiple menu items (in different menus) point to the same path, what is the recommended solution? I find that weird because it is not uncommon for a website to have a bottom menu that repeat some of the links found in the top menu!
