why can't I get FreeBSD-RELEASE-p14 with this cvsup file ?

[Supote Leelasupphakorn]

Hi all

   I've cvsup with below supfile. After finished,
The file:/usr/src/sys/conf/newvers.sh say 

#   @(#)newvers.sh  8.1 (Berkeley) 4/20/94
# $FreeBSD: src/sys/conf/newvers.sh,v 1.44.2.29.2.15 2003/11/27
16:34:21 nectar Exp $

TYPE="FreeBSD"
REVISION="4.8"
BRANCH="RELEASE-p14"
RELEASE="${REVISION}-${BRANCH}"
VERSION="${TYPE} ${RELEASE}"

   Even I specificed date in supfile (the date is from Security
Advisory: FreeBSD-SA-04:02.shmat), it's RELEASE-p14 not
RELEASE-p15. Why and how do I get previous branch of source
tree.

##################################
# My supfile.
##################################
*default host=cvsup2.jp.freebsd.org

Any help is appreciated.
