I think this issue is described inĀ https://emacs.stackexchange.com/questions/50216/org-mode-code-block-parentheses-mismatch. There are also some solutions there.

The following code will evaluate

#+begin_src emacs-lisp
(defun Foo ()
(if (= 2 4) bar))
#+end_src

#+RESULTS:
: Foo
and the opening and closing parentheses match.

If a greater than is inserted instead of equals, thus

#+begin_src emacs-lisp
(defun Foo ()
(if (> 2 4) bar))
#+end_src

it apparently evaluates, however, the closing parenthesis immediately
following the "4" is paired with the opening paren before "if" and not
the opening paren immediately before the ">"

A "less than" results with stranger parenthesis matching - the closing
paren after the "4" matches no others; the closing paren immediately
after "bar" matches the opening paren before "if"
