They have also lost to the likes of Wales, Austria and Iceland (both very heavily) who are way down in the rankings in the same time period so why are they so high? The rankings are a nonsense.
Why are Brazil and Argentina higher than France and Italy? Both far better teams if the World Cup is anything to go by though to be honest I can now see the logic in giving the same weighting to games in the Copa America against pretty laclustre teams than quarter final results in the World Cup.
