No, the post_author_meta_box lists all eligible authors, not just
administrators.

It calls this function:
wp_dropdown_users( array(
		'who' => 'authors',
		'name' => 'post_author_override',
		'selected' => empty($post->ID) ? $user_ID : $post->post_author,
		'include_selected' => true
	) );

Eventually that "who" field makes its way down to WP_User_Query, which
interprets it as being all users with a usermeta field of "user_level"
that is != 0. Which is essentially all the users on the blog.
