I'm guessing that comes from `bindings.el' binding `M-r' to `previous-matching-history-element' in `minibuffer-local-map', and Icicles binding `M-r' to `icicle-roundup' in `minibuffer-local-completion-map'.  And this is true:

(eq minibuffer-local-map
    (keymap-parent minibuffer-local-completion-map))

I'm guessing that's what all the "shadowing" is about.  `icicle-roundup' is the actual binding, in `minibuffer-local-completion-map'.  Why, in a listing of `minibuffer-local-completion-map', we show the other command as also being bound to `M-r', I don't know.  I don't mean how we do that, but why - for users?
