Ah okay I guess it would be to do with things like sugar or protein in the drink slowing down the absorption. It's mostly sodium and potassium that would make a drink more hydrating but need to be careful with things like that as well especially in the heat and or if someone is training hardI can't remember exactly, but I think it was a personal trainer if it's just water it'll go right through you but if it has juice then it works the body better.
For example I just found out the recently popular Prime drinks are marketed as hydration beverages but actually contain very little sodium to be that.
Also heard of a case of a guy who played tennis in the heat and was hydrating himself with coconut water, which is high in potassium and almost died
