Yes, subdirectories inherit their parents <DirectoryDirs> and
<AppDirs>. Its kind of hidden in the language:
"Each directory listed in a <DirectoryDir> element will be searched
for directory entries to be used when resolving the <Directory>
element for this menu and its submenus."

I'm not sure I follow what you're saying, but having
is exactly identical to having
so all submenus of the <Menu> that contained <DefaultDirectoryDirs/>
should also search the default dirs.
