No, those two examples do _different things.

the first ignores a client which is not know OR  blacklisted, the second
ignores a client which is not known AND blacklisted.

Since a  client has to be known to get blacklisted, the second isn't
useful, it has no effect.

The syntax changed to make is clearer. The old syntax (# for NOT) is
still supported for old config files, but the documentation was updated
to reflect the new, prefered way of doing things.
