The behaviour is roughly what should be expected. It's helpful to keep in mind that the jail isn't running a getty or login process in the context of the jail. So using jexec -U blog blog tcsh you'll acquire the correct ID, but be dropped into '/'. Reading the jail code might be the only definitive statement as to why. When you ssh into the jail, there is no tty assigned to the session. You can force a tty by ssh -t katana jexec -U blog blog tcsh Which should give you what you require, a shell within the jail context and an id of blog.
