I complained about that, but it was too late to do anything about it. (You don't usually even see those frontmatter pages during the book-writing/editing/proofing process.)
Why complain? It's a little funny: the latter paragraph ends "... without the prior written permission of the copyright owner and the publisher", which, apparently, the former paragraph grants. No?
I'm not sure this is the case here, but it might be the difference between the actual text itself and the representation, arrangement, and style of the text as exhibited in the book. This happens in music, where a given Mozart concerto, for example, is in the public domain, but that doesn't mean you can photocopy a given sheet music of the concerto and hand it out; the notes themselves are in the public domain, but the particular typesetting of the specific document is not.
This was an issue recently with the Google Book Search deal. Even though the books were out of copyright or orphaned, Google owned the copyright to the scans, and would only give a non-transferable license back to the universities.
Google does have a copyright on the collection as a whole, even as they do not gain any extra rights on the underlying public domain material. It's sort of weird, but it does make sense.
I see the first paragraph as being "written permission" to "copy distribute and/or modify" the document under some quite specific conditions, and the second as reserving all other rights.
These two paragraphs are pretty odd sitting next to each other: http://timfreeman.org/copyright_dip.png
