It isn't. It's just a hokey name for a FAT32 volume that happens to
live in a type 0x0C partition (as opposed to a type 0x01, 0x04, 0x06,
0x0B, or 0x0E partition). The filesystem type is the same, FAT32, in
all cases. A type 0x0C partition is, simply, supposed to be invisible
to operating systems that suffer from the 1024 cylinder limitation or
that cannot handle partitions greater than or equal to 2GiB in size.
Thus it can begin/extend beyond the 1024 cylinder boundary and be
larger than 2GiB. This is irrespective of filesystem format. Indeed,
depending from its size, such a partition could just as easily be a
FAT16 volume, or even a FAT12 volume, as a FAT32 volume.
