That is only for non-filesystem labels, according to glabel(8):
"This class also provides volume label detection for file systems. Those
labels cannot be set with glabel, but must be set with the appropriate
file system utility, e.g. for UFS the file system label is set with
tunefs(8). Currently supported file systems are:
o UFS1 (directory /dev/ufs/).
o UFS2 (directory /dev/ufs/).
o MSDOSFS (FAT12, FAT16, FAT32) (directory /dev/msdosfs/).
o CD ISO9660 (directory /dev/iso9660/).
o EXT2FS (directory /dev/ext2fs/).
o REISERFS (directory /dev/reiserfs/).
o NTFS (directory /dev/ntfs/).
Non file-system labels are created in the directory /dev/label/."
