Maybe it's a poor example then, I wasn't aware of that.
Mobile BankID (Scandinavian Identity Service), my British Banking app and Okta verify definitely can't transfer to a new phone. I know because I checked recently.
My overall point is: they're not alone, this is a common issue for Apps.
My (Swedish) BankID definitely doesn't run from the sim card. :S I've had 4 phones in Sweden and I had to enroll it as a new device each time in Nordea.
