If that worked at all, it was accidental.

If you locked out everything then you didn't have the "allow" logic that
you thought you did. :)
I'm sure you know that if you have an allow statement, everything that
is not allowed is denied. And the opposite is also true, if you have a
deny statement anything that is not denied is allowed. That makes things
slightly more complex at the outset, but once you learn the logic, it's
pretty simple to work with.

Confirmed. The behavior is not deterministic. Explicit allows and denys
are the way to go.
