Yes, the Spec II title can be read to be a bit misleading. But if you compare Spec II with Spec I (the base game), it makes some more sense in my opinion.
Personally, I think this re-release is good news and here's the reason why.
This re-release is aimed at getting new sales in the run up to Christmas. The money from those extra sales will, in my opinion, provide some funding towards the upcoming updates which I think will remain free (at no extra cost) for longer as a result. We don't know how significant any updates will be, but we do now know that they will run on at least until the release of the Porsche VGT in the second half of 2020.
It's the same idea basically as the not compulsory microtransactions for cars. In my opinion they are trying to find alternative ways to fund the cost of DLC as they are not directly charging for it. Those salaries have to be paid by revenue from somewhere?
