Otherwise the nomenclature does not make sense: it is not a double rattrapante, or is it?
No it is a double chrono that can be used saperately, too

I will read the article about the DS again, but as far as I understood, and the author was speaking clearly
about a refence time that can be displayed and saved graphically, and new time measurements can be done
again and again.
Really sorry that I struggle a bit to read your post completely.
