*diff* is an ephemeral buffer, there is no documented value of its
`default-directory'. I guess you describe a side-effect you're using.

And I cannot reproduce your problem. If I am in a dired buffer, and type
"=" (dired-diff), I get a *diff* buffer with the expected
`default-directory'. 'C-x C-j' works as expected for me.

Could you pls show a recipe, which highlights what is broken for you?

Best regards, Michael.
