Using the same example as in that thread, I get the following output:

Notice the +hello vs. -hello in the last line off the diff. Git with
your patch on the other hand gives me +hello in both cases.

So while I think the behaviour with git diff --no-index $directory $file
is correct (minus the comments by Matthieu), git diff --no-index $file
$directory is not, I think.
