Yet they are:

I suspect that's simply because no country uses both the ISO B and JIS B series, so there's not need to tell them apart usually.

I am not so sure that printer models are the same everywhere (let alone paper trays).

We could do that, but I don't think there is much doubt about the fact that:
* The B series is in common use in Japan
* The B series used in Japan is the JIS one

Here are two extra source, and google will produce many more if asked:
