Graham, i followed your steps here on my system (iMac 5K and Thunderbolt display). It works here without problems.
Maybe it works here, because i have setup that my monitors use different spaces. You can set this in SystemControl->MissionControl. I do not know the exact english expression as i have here a german Mac OS X running. One of the advantages of this option is that i can run other programs (in my case DVD-Player) in fullscreen on one screen and the other screen is still visible and not black. Maybe you should try that set this option in mission control too.
