The speed indice is cut for 400, and depressing the camera's filter pin with a notchless cartridge will set the SMPTE 'daylight' speed for that particular speed indice, which would end up being ASA 250. That's how they get it.
Same with V100T-- speed indice is ASA 160T/100D, notchless cartridge pushes in the camera's filter pin, which then sets the meter at the ASA 100 (the daylight 'D' ASA). Cut a notch and you'll get an ASA 160 setting instead.
A notchless cartridge also disables the internal 85 filter-- so basically Kodak sets up their S8 VISION tungsten stocks to read as daylight films with the lower ASAs. Why do they do that? Because they think a one-stop overexposure is best, and not to use a worn out internal 85.
By the way, Kodak's 2002 information on that web page is wrong about 7217. The notches all set the V200T cartridge to ASA 100 in most cameras, not 160. This has caused an immense amount of confusion over the years.
But it's really not much to worry about-- these films work well in most auto modes no matter how they rate, that's how much latitude they have.
