I believe you're right - the system you describe is not the visitor 
pattern (or an extended versino of this pattern).

Small thing here: the visitor pattern is not working over data - it's
a general selector. Since it's goal is to emulate multiple dispatch
in languages that lack this functionnality, it is neither data nor code
oriented. It just selects the right path for the right parameter types.
