Why can't unexpected questions and comments go in the lower pane?

In Symbolics 3600 Zwei in System 242.356, Hardcopy 20.10, FEP 22, on Lisp Machine Sid Vicious:

For instance, if I do a M-X Save All Files, it asks me questions by
typing out over the top of the buffer.  Worse, if it does nothing it
prints "Done." invisibly at the top of the screen.  Why can't query-io
be bound to the lower pane?

PS: this also applies to e.g. c-sh-e, or the message you get when you
try to write over a file that has changed.
