That's what I thought when I saw it first, too. But I duplicated that setup (actually only used 3 tubes, for just one circuit at a time) and it was surprisingly easier to work with than the normal procedure with a single tube.
The point of that exercise was that I could install the tubes when everything was nice and dry and I could work the nipples without spilling and splashing, without having to move the tubes from one nipple to another.
I know it does look weird, but I am a convert to this method now.
