The above 10-string, double course guitar bridge has a table to set floating "saddles" for each pair of strings.

So they float like archtop bridges? I would imagine they would move as you tuned the string to pitch.

Comes to mind that I mentioned a few years ago about a classical builder who drilled individual holes part way into the bridge to set slotted brass pins for each string. I suppose something along that line could let you adjust each string with a new pin, without having to interfere with adjacent strings.

I'm wondering why you referred to them as "floating" saddles. The bridge isn't described in the listing. Did you find info about how Vergilio Artur de Lima makes bridges like this somewhere else?

No, I just jumped to conclusion that it did not look like the little saddles were recessed. Maybe they are attached.

The compensation scheme is interesting/puzzling. I wonder what the reason is for the angle of the saddle for the bass-side string pair. Based on the builder's website this use of separate saddles and how they are set for compensation is standard procedure for him on this instrument. I looked up pics of violas caipira from other makers and they use single piece saddles similar to what you would typically see on a twelve-string guitar.

Here's a photo of a part of a "14-string double-tuned guitar" of his. It would interesting to see the rest of the instrument to see what's going on there.
