I don't think this is unusual behavior; there are several places in
Emacs that uses similar behavior.  The idea is that the *Keys* buffer is
used to navigate through the list of keys, and the other buffer displays
the keys to view.  It would be annoying to move point into the viewing
buffer, because you can't do much there.

(For similar behavior see, e.g., the summary buffer in Gnus.)
