booting two freebsd slices from syslinux (boots always the first freebsd slice)

I'm trying to make bootable USB flash for servers install and recovery.
To make it one USB for all my needs, i've come to this partitioning scheme:
% gpart show da0
=> 63 15734721 da0 MBR (7.5G)
63 8241282 1 fat32 [active] (3.9G)
8241345 3071943 2 freebsd (1.5G)
11313288 3071943 3 freebsd (1.5G)
14385231 1349523 4 freebsd (659M)
15734754 30 - free - (15K)
% ls -l /dev/da
da0% da0s1% da0s2% da0s2a% da0s3% da0s3a% da0s4% da0s4a%
First partition is fat32 with HP SPP on it, which is booting by syslinux
Second is for FreeBSD 10.1-R 32bit system (root mounting from
Third is for FreeBSD 10.1-R 64bit system (root mounting from
Fourth is common to both FreeBSD systems /root folder.
To make 2nd and 3rd partitions bootable i've make them with 'bsdlabel -B -w
/dev/da0s2' and 'bsdlabel -B -w /dev/da0s3'.
Here comes syslinux.cfg:
MENU LABEL FreeBSD 32bit
APPEND boot 2
MENU LABEL FreeBSD 64bit
APPEND boot 3
MENU LABEL FreeBSD 4part
APPEND boot 4
While booting if i choose label for "fbsd32" label, it boots 32bit system
from da0s2. And when i choose "fbsd64" label it also boots 32bit system!
I've make "fbsd4" label for testing purposes, it tries to boot from da0s4
slice and it's not booting since there are no boot code in it.
Why does it boot from da0s2 system when i choose fbsd64 label? How can i
debug booting process?
