The NaOH is just added to convert the particles into ones which can participate in the titration.

In the reaction with iodine, sulfur dioxide gas is released

judging by the reply, perhaps the NaOH "Frees" the SO2 from a "fixed" molecular state? Or a different molecule overall? is there any other information given?
