I'm not sure he's thought this through
I don't see anything wrong with what he's saying. He's just saying he has the option to play for the US if they want him to. It's obvious to all that they won't, but nothing wrong with reminding NZ football he's keen to play for the AWs.
He's played for the U20s so if he's not keen to make himself available for NZ then perhaps that might have been the time to raise it.
The reason I said he hasn't thought this through is either he thinks he has a chance to make it with the USA, which I think we'd all agree is a little over-ambitious considering where he's at in his career, or he's trying to force the hand of NZF, which I personally don't like, or he's just been a bit naive, which I think is probably the case.
He says it's going to be a hard decision but really it's not when one country isn't going to pick you.
He never said he's not keen to play for NZ. Someone has asked him if he'd play for the US if asked and he's said he's not sure. I think that's understandable considering he's spent a big portion of his life there. Nowhere in that article does he say he realistically thinks he has a chance of playing for the USA. I'm not sure what he's expected to say - the reporter was just digging for a story and made a headline out of nothing.
