That is correct. There are however no problems to add an FSF style grant back, since we've never actually considered suing someone for using his code.

So I take it there's actually no grant-back as in the FSF case? Then it's probably necessary to explain how the use of MPL or LGPL makes the absence of that a no real restriction.
I believe it would be simpler to have an FSF-style grant-back. That would probably feel more free for the contributor.
