The reason the spots look different is because an aussie is a longhaired breed -- spots look more defined on a short haired breed. Compare the merle spots on a rough collie to those on a smooth collie. The smooth collie will obviously have markings more like a catahoula. Either way, it is still the merle gene -- there is no "difference" between merle in one dog, and merle in another.
