Actually it goes much further. If you sue any author of any AFL- licensed software for patent infringement, you lose all rights to *all* AFL-licensed software, as well as all rights to all other software with that same "poison pill" clause. Currently that means you also lose rights to all OSL-licensed software. The GPL has its own implicit patent poison pill, which works as you describe above. That's because enforcing a patent right is imposing a "further restriction" in GPL terms.
