Example.

Say I'm employed, and I'm working on some project for my employer. I download
some GPL'ed code, and write some nontrivial additions to it.

This now means the institution has the copyright on the code I wrote. If I'd
want to distribute this software, I'd need 2 things:
1) distribute it under the GPL
2) ask my employer to either:
  a) grant me my copyright back on the additions
  b) give me permission to distribute the software under the GPL

If I wouldn't do (1), I would violate the copyright of the original author of
the GPL'ed code I download.

If I wouldn't do (2), I would violate the copyright of my employer.

In other words, if my employer doesn't give me permission to distribute the
work I did for him, I cannot distribute it at all, regardless of the GPL.
The instition is still bound by the GPL though, so they can't distribute the
software under anything other than the GPL - but they can still choose not to
distribute at all.
