It is the test case which need  this topology, for some test you only need
one other simulated node, for others more, so if you look at the network traffic
in the test network, it would look like that here are different nodes, 
but all nodes except the NUT on the net are simulated by the testing node
(running the test suite). This is standard for test equipment.
You may see that like the testing node has multiple virtual machines which
represent all nodes in the network, except the node under test.
