Just looks like bad design to me.
You have a point Allan but I suspect the time and or money wasn't in this project to cover the R&D necessary to come up with such a design?

Gerd Neumanns enginering skills are first class so I am sure it must be adequate if La Silla have ok'd it..?

FLI's CentreLine (named by me incidentally!) is close to what you are suggesting.
