OK, so I'm saying that when invoking Dired, I see the same numbers
(both of them) no matter from which buffer I invoked Dired.  Even if
the default-directory of each buffer is on a different drive.

With your recipe, indeed the free space is not always correct.  But
why is that use case interesting?  insert-directory is not a normally
a user-visible function.
