You are correct. It complains about duplicate hostnames. 

If you slightly change the hostname, for one section, it should work. I
know it doesn't force the hostname onto the machine. Because, when a
physical machine name is changed and the MAC is the same we still get
these addresses pushed out to the machine. I think you have another
option for that called server-name. 

Hope this helps,
