I think that part is out of date. Per
https://help.ubuntu.com/community/RadeonDriver
which is for ati video cards, you should be able to use any name you
want to for the monitors.

Here is another page on the community help wiki that might help:
https://help.ubuntu.com/community/Video
Basically, they refer you back to the ati page for dual head (dual
monitor), https://help.ubuntu.com/community/RadeonDriver#MergedFB
You may need to define 2 screens in the "ServerLayout" section. I only
see one screen defined now, which may be why they are clones.
good luck,
