Wasn't that already explained?  What happens if you say

  (setq-default lexical-binding t)

and then load a Lisp file that expects dynamic-binding by default?

IOW, the lack of lexical-binding: cookie in a file is interpreted as
having an explicit "lexical-binding: nil" in that file, for the
reasons Tomas explained.
