I've just created a fusion drive and everything's working as expected 
I'm on a late 2009 iMac 27" with a samsung 830 256GB in the optical bay.
When I boot with the alt key I get two (same name) disks to choose from. They both bring me to the same desktop (there's no additional disks connected).
Any ideas?
this is what I get running diskutil cs list:
