Yes, I noticed that problem the first time I tried this setup two years ago. The solution was to leave the swivel in play, along with a shackle thru the hole, rather than ignoring the swivel altogether. The biner is thru both and the shackle is carrying most of the load. The swivel is not under any real pressure but does keep the whole rig level. Here is a shot of it as it looks loaded. You can see the links are only about 2/3 of the way towards the outer stop. I have two of these combos, on each end of one of my main ropes, for leap-frogging the TIP up a tree by swapping ends of the rope. The bottom of the photo is not all that clear but you can just make out the swivel with biner thru it.
