Radius proxy question?

Hi, I'm wondering how a radius proxy differentiates between certain groups I add to it?
So I add group1 for domain 1 with an address to a radius server and group2 for domain 2 and a address to another radius server, both groups have different domain names for them (obviously), but there doesn't seem to be anything popping out to me that says when some from domain 1 is logging in, they go to group1. How does the radius server know what domain needs to he sent to what "group"??
Thanks
