Babel: verbatim results yield a table

[Jarmo Hurri <jarmo.hurri@iki.fi>]

Greetings.

The org manual states that in the :results header argument of a block

verbatim Interpret literally and insert as quoted text. Do not create a
         table. Usage example: :results value verbatim

The quote above is from https://orgmode.org/manual/results.html

Given this description, I am trying to understand the result below from
a Scheme snippet (this is an exercise in the good old SICP). In
particular, why is the table created from the (nested) list?

   #+BEGIN_SRC scheme :exports both :results value verbatim
     (define (deep-reverse lst)
       (define (deep-iter lst result)
         (if (null? lst)
             result
             (let ((first (car lst)) (rest (cdr lst)))
               (deep-iter rest
                          (cons (if
                                 (pair? first)
                                 (deep-reverse first)
                                 first)
                                result)))))
       (deep-iter lst '()))

     (deep-reverse (list (list 1 2 3 4) (list (list 5 6) 7 8)))
   #+END_SRC

   #+RESULTS:
   | 8 | 7 | (6 5) |   |
   | 4 | 3 |     2 | 1 |
