I think this is because Emacs 25 exports to the environment of the
subordinate Emacs its value of emacs_dir, which then points the
subordinate Emacs at the directory where Emacs 25 lives.
Emacs 26 fixed that problem, AFAIR, so I think if you do it the other
way around, i.e. invoke Emacs 25 from inside Emacs 26, you will see
the expected behavior.
