I think what they're implying is that they can restore _everyone's_ data quickly (i.e. 'usual' infra failure), and one Jira instance's data fairly quickly (but some manual steps), but the problem is they nuked a large subset of customers while everything else kept running. This means that they can't do a complete automatic restore, and instead have to deal with it customer at a time. I'm sure that they're going to make their customer at a time thing properly automatic now... Still a big failure, but a little more subtle than you make out.
