Yes, it means swap partition.  It changes the partition type code to one
that is different from the normal linux one.  mkswap makes the swap
signature, aka formats the swap filesystem.  It sounds like Sebastian is
saying that DASD does not store the swap flag in the partition table,
but rather probes for a swap filesystem and if it finds that, sets the flag.
