That's ... expected, if you think about it.
I just tried it as you are running it, with two different ttys. Ctrl-Alt-F2 is running dd and I logged in on Ctrl-Alt-F3 and issued the kill command. The output is on Ctrl-Alt-F2, where dd is running.
My example failed because I backgrounded dd and did it all from one terminal.
