I cannot help you directly in that I don't know how to /flow/ text (or
code) from one column to the next.  I don't think it is actually
possible in beamer.

However, it *is* straightforward to flow text from one slide to the next
by simply adding =allowframebreaks= to the beamer environment
arguments.  For instance,

#+begin_src org
*** Code example
    :PROPERTIES:
    :BEAMER_envargs: [allowframebreaks]
    :END:
#+LATEX: {\scriptsize
#+begin_example
   <code goes here>
#+end_example
#+LATEX: }
#+end_src

The slides will automatically be numbered using roman numerals should
more than one slide (aka frame in beamer speak) be required.

I use latex directives to make the font a little smaller to ensure that
lines with within the slide width-wise.

HTH,
