Question : Hyper-V Host with two NIC's in the same network

We've got a Windows 2008 Server with Hyper-V. On the Hyper-V is running a Windows 2008 R2 TS. For the connection there is a adapter for Microsoft virtual network switch. This is a virtual adapter beside the physical adapter. The pysical adapter has the ip adress 192.16.128.1. The virtual adapter get the IP 192.16.128.100 from DHCP. How you can see in the route print communicates the host now over 192.16.128.100. Is this correct or a miss configuration? How should work such a virtual network? In school I learned that it is not a good idea to have more than one nic in the same machine connected to the same network. What is the experts suggestion?
