The impression I got was that the existence of a hardware random number generator was unexpected.
The rest was just demonstrating that it works, and produces pretty reliable random output. In order to do that, they used a standard tool that tests randomness. But it's nice to make sure your randomness test tool is actually good; so using it on a known-bad RNG, and seeing that it does fail, is a good way to demonstrate that.
