I guess you imagine the control room is joy-sticking / flipping each individual switch?

The processes are automatically executed, but are check-pointed rather than run end-to-end. This is to make sure partial failures can be detected.

Building the self-sensing and error-recovery logic to support a "level 5" automated unfolding is wasteful of taxpayer money when a few folks can just take a little longer to do it stepwise -- with much less development, hardware, and software cost overall.
