what he said is he is long gold and short the pound against it. if you both buy gold and sell the pound at the same time each time you do a transaction in the same amount it basically makes it as if you purchased gold in that currency rather than in dollars. so basically he is saying he's not sure what the US dollar is gonna do, maybe there will be some crazy flight to safety causing gold to go down again in US dollars, but that shouldn't happen to the pound, so hopefully it'd still be breaking new highs there. i mean if a pound were suddenly parity with the dollar gold could be trading sub 800$ and still be in new highs when measured in a different currency. hope that helps
