I saw repository on GitHub where someone had LICENSE file as below:

I have read that Apache2.0 license must be copied into LICENSE file, and then the NOTICE file will contain exactly that what I showed above.

If the license was invalid at first time, then can someone say "your code at some moment wasn't licensed, so I created repo with your code and added copyright on my name"? And if license was fixed, then does still someone could do it, because "law is not retroactive"? If yes, what this poor man should do to have copyrights?
