Well, it's maybe non-obvious. The binding string begins with ESC, which
is by default the meta-prefix for emacs mode. That means you do the key
binding in the `emacs-meta' keymap.
The `-u' option to bind operates on the default keymap, which in emacs
mode is `emacs'.
If you add the `-m emacs-meta' option to your `bind -u' command, you'll
get the results you want.
It might be better if the underlying readline function descended into
keymaps such as emacs-meta rather than operating on a single keymap, but
it doesn't do that right now.
