OK, I get it.
It's like an extreme version of metal tape measures. Which are ~flat when rolled up, and then curve enough when unrolled to become ~rigid. But in this case, they seem to become almost cylindrical when unrolled.
I know that it's likely an old design. It's just that I know nothing about satellite design.
