from the same page you got that from it also say this:

so as I have said a couple times now....if I claim I have created something that you created but you do not put it on pager (copyrighted) I can claim that I created it a week before you and actually copyright it and you cannot do anything about it and I will actually be the one who can sue you for claiming it is yours.

these things are worded in such a way that can be confusing to many and many usually stop reading when they see what they think is the answer to their question. You have to keep reading because laws routinely contradict themselves and it is left up to the lawyers to argure it out.

if you don't register your work....you cannot complain if someone steals it and registers it as their own

Actually, you are completely wrong.

Copyright is different to trademarks or patents - you do NOT need to register it. You do NOT even need to put up a notice, though people do it to ensure others respect their copyright.

If I write a book, compose a song, or design a website, the copyright belongs to me as the creator - automatically. It's part of common law though legislation in all jurisdictions protect this fundamental right too.

Hope this clears things up.
