Subscribe and Save TopCashback Re Subscribed Order?

Hi just wondering if anyone knows with Top Cashback on Amazon subscribe and save it says you only get cashback on your first order

I always read that as being if you subscribe and save and then cancel the subscription and then later try to get cashback if you subscribe to the same product again you won't get cashback

But now I'm thinking it just means you only get cashback on the first order in that subscription so you'll get cashback on subscription order 1 but not cashback on order number 2?

Which means maybe if you subscribe and save, get cashback, cancel the subscription and then subscribe and save again on the same item you will get cashback again on that re-subscribed order does anyone know?

Thanks
