Would this affect a new repo I make if it's named after one I renamed before?

My testing:

1. Create https://github.com/beefsack/test1

2. Rename to https://github.com/beefsack/test2, redirect works

3. Create new https://github.com/beefsack/test1, link from (1) points to this new repo

So yeah, it looks like it works.

No, because it would still have a different owner, same as forks do.

He's talking about if it's by the same owner (him). See beefsack's response which answers this question.
