That appears to be a Harken swivel, it is not 2 seperate swivels. Turn it over (end for end) and the attach it. It should work just fine. The bow shackel will attach the swivel to the forestay and the other end should connect to the shackel on the mast tang by using the clevis pin in that end.
The lower one is a Harken swivel and should be turned around. The swivel he is holding in his fingers old style should be removed. He can use a pig tail or plate like the nacra style to finish hooking up the top.
