It is the number of FATs, not the cluster size, that is always 2. GEMDOS
ignores the number of FATs parameter in the boot sector, and always
deals with the disk as if it had 2 copies of the FAT.

Cluster size is properly supported, and can vary from disk to disk. 2 is
the merely the default cluster size.
