I'm not 100% sure as I didn't get to that lab, but I think the one piece of information that would help is that host pools inherit their other properties from the network pool that the host ip matches. For instance if you have a pool for 10.10.0.0/24 and a host pool 10.10.2.2, that host pool will inherit any settings of the network pool 10.10.0.0/24. I'm guessing that the VRF configuration would also be inherited, that's why you need the network pool and the host pool together.
Hope that helps.
