Subscriber ID not reset

I got to know that “If you cancel all your subscriptions with a particular developer and do not resubscribe within 180 days, your subscriber ID will be reset”.

For me, it has been over 180 days since a particular subscription expired, but I can still see it popping up in my subscriptions tab.

Is it because I let it expire instead of cancelling the subscription? If so, I permanently deleted my account for that app within the subscription period itself so; do I need to go back, create a new account from the same email ID, re subscribe and then cancel it this time instead of letting it expire?

Is there no other way to reset the subscriber ID, because having to re subscribe (pay for it) just to be able to cancel it so my subscriber ID can get reset is extremely inconvenient and roundabout method
