I don't think it works that way. Keyclone, from my understanding, repeats keystrokes set to the active window, not so much sending a new keystroke to all of the windows you've selected Keyclone to work with.

If he'd grab, then send out to all of the windows, I'm sure Rob could code in a check box kind of thing to drop the current focus window repeat al la round robbin functionally.

Who knows, I'll PM him this thread.
