Twisting is about adding common mode rejection. When the wires are twisted together, what noise goes in + wire is canceled by the noise in the - wire of the pickup cable. So it is possible to be lucky and have the sensor wire more together in parallel and not intertwined enough with the coil wire. If one is more parallel with the coil wire, there can be coupling of the ~400V transient there, with the 2V pickup signal when cranking. It is a relative thing, if noise exceeds are certain margin, then no-good-worky, and some problems go unnoticed. Not many use a scope, and view the necessary waveforms.
I am old fart industrial control electronics design guy, and a bit AR. I use a twisted pair shielded cable with a ground at one end, and a separate cable for power and ground to a real ECU. However with all said, the Mopar variable reluctance distributor is not my choice. I am a Optical or Hall sensor guy, for a few good reasons.
