Not to pick on you, but it's obvious you've never used the product that you are defending. The alkalinity is way high (close to 13dKH) if you mix it per the directions to 1.025. I believe it was originally intended to replace dosing by providing elevated levels. A common problem with the salt, which Red Sea has admitted to online, is that the additives (dry two part and Mg) have a different grain size than the actual salt and can and will settle out during shipping leading to extreme alk levels when the user pulls salt from that section of the bucket. I would assume that most of the people using it with good results are either mixing it wrong (if you mix it too long the additives will precipitate out and you will get a lower alk level) or are doing small enough WCs that the rise in alk doesn't crash the tank.
