as the author of of ob-picolisp I should make some smart comment now,
but I'm afraid I cannot add much to the discussion, the former answers

to work fine, so the original problem looks not really ob-picolisp
specific but rather like a problem with using Org code blocks correctly.
Here is a link to the relevant manual section:

This is not related to PicoLisp namespaces but rather to the
communication between Emacs and PicoLisp.
- without session, Emacs/Org-mode starts a new PicoLisp instance for
every query, so e.g. setting X to 3 in one code block and then adding 2
to X in the next code block won't work, since the newly started
instance for the second call knows nothing about X.
- with session, Emacs starts one PicoLisp instance and keeps it
alive, so that state is preserved. The call from the second code
block goes to the same PicoLisp instance where symbol X was set to
3 before, so the state of X is preserved and can be used for (+
X 2) e.g.
