You'll need a Sparky to answer this.
BTW, I found at least one logical inconsistency in the NEC. If you believe that statements like
"If the shoe fits, wear it"
says anything about the other three cases then you also may be mislead by the NEC.
To me, the NEC is slightly less arbitrary than the 6000 page Tax Code of the U.S.. But I think there is a bias in both. . .which is that the U.S. Treasury and the NEMA will never come out on the short ends of these sticks when dealing with the average homeowner or taxpayer.
From a physics point of view, high and sustained contact force over the life of the device in a splicing method is virtually as safe as a non-spliced cable because it reduces the contact resistance to near zero. For the real world, splices are contained in fire-resistant boxes.
