Hmmm, the code example you posted does not show index() calling
show(). That the form had it as the target of the action doesn't
result in index() calling show() within the code.

What the docs is referring to is that the Session object will look in
the session database to see if an existing persistent session entry is
there from a previous request, not that it will look to see if a prior
Session object instance has been created for the current request.
