How is being 'properly basic' at all a guarantee that a belief has any relation to reality?

You are correct, it does not mean the belief is true, only that you are justified in believing it (rational). There could exist defeaters that you are unaware of.
Except the rationality would also rely on evidence that it is true. You can make an internally logical argument that does not show up in reality. That does not make it true. The original premise has to mean something before that argument can be accepted to reflect on reality. Otherwise you are not practicing rationality in any way that actually matters.
