wholly for the purposes of education mean just that - you are living in a country because you attend univeristy there. Ordinarily would mean if that was your home, regradless of going to uni there, for example, you may have moved there with your parents before you started studying and you are there as a consequence of that, not because you chose that institution. Hope you get what I mean. It doesn't sound as if you would be eligible, but why don't you try giving them a call. I've always found research councils really helpful!
