Can someone explain why I configure a static route to a loopback network on another router?

I am doing a networking lab for school. I have configured two routers, one with a created loopback address. One of the steps in the lab is to create a static route, from the one router to the other, for its loopback network.

Is this to direct traffic that is meant to the loopback network from the router without the loopback address to the router with the loopback address? What exactly is the point of this? Why does someone need to get into the loopback network from outside the router?

Thanks!
