Maybe it means that you can re-install an identical (bit to bit) library.
Does not forbid Tivo-ization, but at least you can check that you have the real source code - and can rebuild for instance to get debugging symbols.
That would forbid the user to encrypt the compiled library to hide bug fixes he has done, and distributing the sources without those bug fixes.
