The original meaning of "releasing something into the public domain" means giving up all your rights on it - the released piece of code is no longer yours. You, like anyone else, can of course reclaim it as your own and release it in whatever way you like - it's public domain, after all. But by releasing it into PD, you're giving away your original ownership rights.
Under German Law, it's not possible to give up ownership rights - at least that's what the majority of lawyers will tell you, not all of them agree on that one. You can of course hand out very broad licenses that for all practical purposes have the exact same effect - but if you apply the original meaning of "releasing something into the public domain", that's simply not possible in Germany.
