I can see something similar using haskell, if that helps:

--8<---------------cut here---------------start------------->8---
# -*- org-confirm-babel-evaluate: nil -*-

Setting the stage

#+BEGIN_SRC haskell :results code verbatim :exports results
let f = (+1)
f 1
#+END_SRC

Using the function

#+BEGIN_SRC haskell :results code verbatim :exports results
f 3
#+END_SRC

Setting another stage

#+BEGIN_SRC haskell :results silent :exports none
let g = (+1)
g 1
#+END_SRC

Using the second function

#+BEGIN_SRC haskell :results code verbatim :exports results
g 3
#+END_SRC
--8<---------------cut here---------------end--------------->8---

In my example, the function f is declared in one block and successfully
used in the second. The function g is declared in a third (silent)
block, and results in an error when we try to call it in the fourth and
final block. Does this demonstrate the default "session" that Alan
mentioned?
