Did you think it combined the file with the built-in list?

It is. I'm not even sure you misunderstood the XOR, since you wrote that 
it tries each server in the root hints file until it gets a successful 
response. That suggests that you understood that the built-in list is 
used in place of the file if no file is provided.
