You are right, that the concentration of the caffeine was as high as it is in a normal cup of coffee. But the caffeine content was given as an absolute value not as a concentration, so it was misleading. But you are right, it was not a lie.
Their text can be easily interpreted as an comparisons of the large or small lemonade with a large or small cup of coffee. Which is not an unreasonable thought, as 30 oz of Cola has roughly the same amount of coffeine (83 mg) as 1 cup of coffee (96 mg, according to Mayo Clinic).
