Subprocess for bash starts running inside VE 180, begins executing
hi.sh.  It's got a different environment, and expands $HOME into /,
then echoes it to stdout.

_Current_ shell expands $HOME into /root.  Subprocess for echo starts
running inside VE 180, with the parameter already expanded.  (vzctl
doesn't even see the "$HOME".)  It is told to echo "/root" to stdout,
so it does.

Does that sound about right?
