I agree with you. Maybe the programmer/vendor is paranoid.

Not for the programmer/vendor, then he will need the RegCode in order to extract from it the RandomBytes and the VolumeSerialNum to generate the corresponding correct key for the registrant.

A Keygen can for instance have the option for the user to enter a Regcode (Registation code) from a different machine and generate the corresponding ActivKey (Activation Key).
Also just for a gemmick, it could include options to decode the RegCode and ActiveKey to compare the RandomBytes and the VolumeSerialNum.
