Probably because they didn't want to bother. Clutch bleeding is a bit of a pain in the butt, but every time I've done it I feel an improvement in clutch feel, even when done every year.
Brake fluid lubricates and conditions the seals in the system. Bleeding out old fluid also removes contamination which can become abrasive (like worn piston seal material).
Changing fluids well in excess of recommended intervals is key to long term vehicle ownership.
