I don't follow OpenBSD, but my understanding is there has been significant
change between FreeBSD's version of PF and the current version in OpenBSD.
According to the freebsd-pf@ list(which is maybe a better place for your
question) PF version 4.5 is scheduled to appear in FreeBSD 9 so we'll still
be well behind.  I would guess the previous version of the book has syntax
and examples closer to what you'll be using if FreeBSD is your host although
2nd editions often have a lot of useful additions and corrections.
