Forgive me for my brain asking WHY? Seems a gimmick connection for sure.
It reminds me of the question surrounding the Indy car wheels where the single lug nut never cross threads when the torque wrench is applied?

I think you had to supply the Butt. The 4 pieces I had lined up perfectly. I was told they made the inserts in match sets of 2.
Viking has little interest in making the inserts anymore which sought of sucks because it was their thing.
Hopefully they still have some for thier own supply use.
Helmsettrr did thier own double joint too

Metric of course.
It's a pain in the Ass!

Thanks for double roasting my brain. 
Pure gimmick
Gimmick or individualism?
An individualized gimmick?
I would like to know the justification for the redundancy of threaded connections. As a general rule of engineering this a no go. When you have two threads doing the same job one will inevitably be working against the other. The way I have always looked at a cue joint you need something to bring the parts together and something to put them in alignment or keep them concentric. The third part which is probably the most controversial is how much surface contact there should be between the parts for the purpose of "feel". In my opinion the first two points are non-negotiable, the third element is optional. A jointed connection can be quite functional without being optimized for "feel ".

The contact between the faces is, hopefully obviously, most important closest to the outside radius.
At best the nested threads are redundant if either thread is capable of providing the force necessary. If neither is strong enough, the second only helps if they can be individually tightened, or if there is a preloaded axial compliance. In most cases the threads, as you said, are likely working against each other in the 'design' shown.
I would be surprised if there weren't significant instances of galling in these joints.
It used to be the case that people claimed that a cue should hit like a one piece cue, but that obviously isn't happening with a large piece of metal in the joint.
Gimmick because they claimed it had some advantages
