It does!  You probably think that all functions and variables are
autoloaded, but it's not the case.  Autoloads are generated only for
those symbols (usually interactive commands) that have ";;;###autoload"
cookies.  For example, look at "M-x find-library debbugs-gnu" and search
for ";;;###autoload" there.

Yes, because this variable is void indeed when your emacs config is
loaded.  Wrap such configurations of external Emacs packages inside
'with-eval-after-load' as Thomas suggested.
