You are correct, only one tie in point, with a clove hitch.... = EDK....
I always use a PA ( some sort of sling deal ) and the rope. That is two points, I do tie a clove hitch with the rope cause you can adjust the length and the PA is on a locking biner.
Unless I am rappelling, than I am fond of going with just one PA, keep it simple. But that is just me.
