In the past, it was possible for a few people but not for many others.

So I would say that one datapoint still only proves that it's possible for some people, and doesn't prove that's it's possible for everyone (or even necessarily for most people).

Similarly, at Citi, most people haven't been able to get a new AA business card without the previous one being closed, for years now, but a few (over the years) have been able to.

Banks don't always apply "rules" (that we perceive, but that the don't publish) universally, but it's usually hard-to-impossible to figure out why they let a few people do something that don't let most other people do.
