Apple TV 4

Hi guys, I just bought a Apple TV 4 and have some questions regarding installing Kodi on it (non jailbreaked)
I wonder if this is still the “correct” way to install kodi on an apple tv 4: HOW-TO: Install Kodi on Apple TV 4 ..
And, if so, what do you mean with this comment: “This method also requires that Kodi be re-installed every 7 days if you are using a free Apple developer account” ??
Does it mean that if you use a normal Apple ID, you dont need to reinstall every 7:th day ??
All help in this matter in appreciated.
