It seems pretty obvious to me. There were issues getting the old FreeDOS image to run on some of the new hardware. Someone was tasked by their manager with fixing it. They said fuck it and just did this because it was easier/faster than trying to troubleshoot DOS on modern hardware. They showed it to their manager and their manager saw FreeDOS boot and was happy. Until now no one ever noticed because FreeDOS is just the "I'm going to pirate windows option".
