Update to the thread drift: It's actually not all 12 strand hollow braid.
There's more than one way to braid a line, and the more strands, the more ways...
To make a short story long, I'd fiddled with the line in question enough before to be pretty sure it wasn't the same braid as the others. I was almost convinced otherwise earlier. But no.
And I thought it was 8 strands, even thought I know that doesn't make the usual round hollow braid. And the line had a "square" shape.
Which does go along with 4 (or 8 ) strands
So recalling old laboratory days, I embedded it in wax, sectioned it, and looked at it out under magnification. This is the best I could do with no microscope, check it:

I could see clearly from the cut face of the wax embedded line that there were in fact 8 strands, appearing at the face of the cut as 2 parallel groups of three strands at 9 and 3 o'clock in the photo, with two single strands in the outside valleys, 12 and 6 o'clock. Presumably the next section would have the orientations reversed, with single strands appearing at 9 and 3, the new single strands having emerged from the "equatorial" groups of three, with the old ones diving in to make up the number in the new "polar" groups of three.
So here we see an alternative 8 strand braid, neither completely solid nor completely hollow.
What's interesting is that the lines, if the sticker on the winder is to be believed, are rated 360dan, versus the more typical 300 on lines of this diameter. I wonder if this has more to do with the fiber, its processing, or the braid. Interesting.
But it's not interesting to try to splice them!
