The point is that a country in the north won't pass the poles. If they know their geography, and that Guardia is the northern country, then Guardia will be the only Northern country. Porre is east of El Nido, but South West of Guardia. To find a point on a map, you either use grid references, or like in the olden days, located it from the most important city on the map anyway.
So at any rate, El Nido is West of Porre
