This seems to be an ongoing argument in the community.
Yes, Kazuo seems to have what you would arguably call Forskahli.
The picture on the bottom of the first page is a vittatus.
Yes, vittatus and forskahli are the same according to documented research, and that the differences are just regional.
I do believe there are clear differences between the two when you look at these things as far as color, jaw shape, caudal shape, body girth, they do look totally different.
But, the main thing here is not how they appear, it is how these things are being classified by researchers. They do so by counting the sets of lateral scales from end to end and the number of lateral lines from top to bottom. I do not know the exact figures according to Cuvier and Castelnau and so forth, but I do know that they came to the conclusion that the figures matched when comparing FATF and VATF.
