Wells Fargo Autograph Credit Card Airline Credit Question

There was another topic about this but it was closed but really had no answer other than quoting the "rule" (which is my issue).

Maybe someone can clear it up. I got the card on Dec 1st. and purchased a $50 American Airlines Gift Card on 12/21 and got the $50 credit within 3 days. I have NOT yet been charged the Annual Fee.

These are the "rules" for the credit.":

5. Each year, you will receive a one-time $50 statement credit applied to your account when your card is used for your first airline purchase of at least $50. <blah blah stuff deleted> For the first year, the credit will be available at account opening. After that, the 12-month annual airline credit period begins the first day of the month after your annual fee is assessed, then renews every 12 months after that. For example, if your annual fee is assessed on November 10th, your annual airline credit period will begin on December 1st. This credit will show within 1-2 billing periods after it is earned.

I can't tell if they are saying that if I get my annual fee charged on (for example) January 5th I can go for the credit again on Feb 5th, OR since I got a credit BEFORE the annual charge just a couple weeks before on Dec 25th I have to wait 1 year from the annual charge to get it again.
