A human interpreting the prompt would see "asian" as being in contrast to "indian" in the language of the prompt... Not a level of comprehension that can be expected of current models but maybe in a few years (months?).
I'm human. I interpreted Asian as from a non-specific part of Asia. I realise though that "Asian" has a very specific meaning in the US, but it's only the US that does this. For the rest of the world Asian means someone from Asia.
That's kind of what I meant... If a prompt specifies one "Indian", and one "Asian", that implies that the writer of the prompt doesn't think of Indian as Asian so probably from the US background.
There's more than two countries in Asia. Could be one Indian and one Sri Lankan, which is what the old dude looks like to me.
