Create Google+ or Google Group before app is available?

Has anyone found the quote below from this site to be true? I released an app a while back and didn’t have to do that, so I’m a little confused by his statement.

When you publish an app for the first time, you need to create a Google Group or a Google+ community for testers before the link to your app becomes available. If you try to access the link (even using your own Google account) without being a member of the configured group/community, you’re greeted with a 404 page.

Thats for betas when you invite a group of testers that join that group…useless, forget about it

Well, like @Crichton333 said that’s for beta version it like at first when you send out an invite to a group of testers… I don’t think you need to think much about it !
