Why does it say these are not tradable when the 100 AP potions clearly were?

From one of the recent compensations nexon did, many people got 2 100 AP potions. Those were most definitely tradable and lots of people were trying to buy them. Nobody really knows for sure yet if these "new" AP potions during this recent event (5, 15, and 30 variations) will be tradable or not.

In short, should the line "The potion (or, if applicable, its coupon) cannot be stored on a pet, mailed, or traded away." be changed to say something else or be taken out completely?

The AP 100 Potions were tradable by trading the codes for them, similar to trading NX codes. These AP Potions are given as an item directly.
