It's actually a set of words that is no longer necessary as of the year
2000. It's not communicating anything about a granted license, which is
what the Apache License does - it's actually just asserting that the
original copyright holder asserts that they have not waived any of their
rights as a copyright holder. However, the Berne convention grants this
automatically without a positive assertion.

In short - the words "All rights reserved" neither help or harm anything.
