See the "DISPLAY NAMES" section of the X man page:

Configure a system with multiple graphics devices or a multi-head graphics
device, and configure them as separate screens, not using Xinerama, MergedFB,
TwinView or other options to merge multiple screens into one.

Run multiple X servers on different devices (physical or virtual).

They don't. Only one X server is used, the one on your local FC10 machine.
X clients (such as xterm, firefox, etc.) on the remote FC10 machine connect
to the sshd on the remote FC10 machine, using it as a proxy to reach the X
server on your local FC10 machine. The remote FC10 machine does not need
to run an X server at all.
