The device used is irrelevent (as is Facebook) - it's the Gamecenter Account that matters. Even if your brother was using his iPad (not "pod") but you log into the same GameCenter account it will be that GameCenter's park. The park itself is stored remotely, restoring your iPad to factory won't affect anything but the local park on the device.

If you log into GameCenter and you see your brothers park, you're using the same GameCenter account as him and you need to create your own GC account separately.
