Where was that? From what I have seen he usually aims to put a tire onto a wheel that matches the section width. I also come from a Miata background where we ran 245s on a 15x10, but again, Hoosier sizing is not real and a 245 15" Hoosier will measure a different width than a 17/18".
Andy Hollis has stated multiple times that a street tire will basically always do better on a wider wheel, Hoosiers are the exception but there are still benefits to going wider.

Yeah I've heard that, but that's not what I see here. Perhaps they're no longer massively wide cheater tires? They were about same as Hankooks. Sure, wider wheel helps, but for a properly setup car, wider tire still always does better lap time than the narrower tire on a wider wheel. I'll need to find that test : )
245 Z214 vs Hoosiers. They look pretty similar in width, and Hoosiers don't seem much bigger.
Depending on how you hold it, it measured around 245 to 250 mm (Hoosiers)
For reference, RT660 225/40/17s measured around 220-225 mm.
