American Express Cardholders: 4-Month Panera Bread Unlimited Sip Club Trial Expired

I've seen this before.. is this a "refreshed" version of the amex promo that has a limited amount of redemptions?
Does it stack with the current (ends 10/5) free 2 months sip club offer right on their app? I'm in a current sub that ends middle of month and contemplating open an account under wife's name if this might expire due to hitting a number of subs...

Can you cancel immediately and still have access the full four months?

No reason I couldn't sign up for the 2 month free trial (available to any non-active subscriber), wait for it to end, then do this 4-month one, right?
