It means the domain conf will be saved on your disk, e.g.
/etc/libvirt/qemu/$domain.xml. Without specifying it, your
domain will be disappear after destroying, that means your
domain is transicient, opposite meaning of persistent.
This might help explain the difference as well:

There is also migration info on that page, but it's fairly basic so
not sure how useful. Worth checking, just in case though. :)
