When you issue a PC-ss instruction, when the PC routine gets invoked, HOME is unchanged. Primary becomes the ASID of the PC routine, and SASN depends on the definition of the PC routine, and will either be the same as the address space that issued the PC (SASN=OLD), or the same as the primary (SASN=NEW). Now if that PC routine issues another PC-ss instruction, HOME again is unchanged, but the Primary and the secondary are again dependent upon the PC routine definition, but will either be the ASID that issued the PC or the ASID that the PC runs in. So now PRIMARY != HOME on PC-ss.
