There are two types of bi-wire speaker cable configurations, one is an internal bi-wire cable configuration, the other is an external bi-wire cable configuration. The internal bi-wire cable type means a single run of cable features two separate sets of conductors within the cable, some intended for the high-posts, the others for the low-posts. The internal bi-wire cable conductors are terminated with one pair of connectors at the amplifier end, and two pairs of connectors at the loudspeaker end. The two conductive paths are kept separate all the way from the amplifier output to the two separate sets of bi-wire binding posts, so it completely follows the concept of bi-wiring to avoid the back EMF of the woofer from affecting the tweeter. However, it's better to use two completely separate runs of speaker cable, one for the high-posts, and the other for the low-posts, that are joined together at the amplifier end with a single set of connectors, which is called an external bi-wire cable configuration. Two separate runs allows the high-post conductors and low-post conductors to be spaced far enough apart from each other to eliminate the influence of magnetic fields between the two separate cable runs, which is a worthwhile thing if one wishes to better avoid interactions between the two conductive paths.

I could just stay with what I have except for the WAF factor that my wife doesnt care for even one run of wire much less two of them - LOL.
It would be interesting to see how these "single run" biwire things perform given that they don't really hold to the whole rationale of biwiring, and as you say even a double run inside the same jacket might not be "purist" but I think largely keeping the cables separate, even if close to one another, might fulfill most of the rationale of it - possible "fields" interfering but the wire itself not occupied by the whole signal
I personally have a suspicion it might have to do with the amount of conductor - both in the cables themselves and also the contacts to the speaker - but of course I can't be sure. I could try blind testing but nobody here cares enough about it to help me with that

Perhaps you should have posted the question in Cable Asylum where the topic is considered from a productive perspective based on direct experience rather than conjecture.
