Odd stitch on the piping of an old LV Saumur bag

I'm tearing down an old Louis Vuitton 'Saumur' bag from 1994.  I was beginning to remove the piping and I notice that the stitch holding the piping to the canvas is unusual.  One side (wrong side of the canvas) looks like a conventional straight machine stitch.   But on the canvas side, the stitch is odd -- there is some kind of looping going on where there are two segments of thread linking each set of holes.    I haven't noticed such a stitch on any of the binding tapes or the handles/straps of the bag.

Wondering what/why this stitch is?  More of a curiosity -- when I put the bag back together it'll have to be a conventional machine stitch.

So on further investigation, I think why i'm seeing the weird stitching on the piping is that it's first folded and sewn together with one stitch,  and then that folded-piping assembly is stitched into the binding-tape/canvas sandwich.

However, the bottom of the folded-in-half stitch itself looks weird with a bunch of extra loops.

it´s a 1 thread chain stitch as it seems

That is a 'cable' stitch. Quite common on fabric items where strength of the sewing is needed. It can only be done by hand sewing

As usual; two names for the same thing,
