I recall reading something about this on Dashew's blog a while back. IIRC, he said this design was multi-purpose:
a) Could accommodate much larger tenders this way,
b) Could use the booms vs. crane in more flexible ways for hoisting supplies and equipment aboard,
c) Could use existing structure without additional reinforcements elsewhere, and
d) Could use booms to double as either flopper-stoppers or as booms for a get-home sail rig.
I might be conflating some different design points he made as I read it last winter. But there were some multiple-use aspects to that design element and he addressed them in a specific blog post about it.
