It doesn't matter. This is marketing fluff. What companies like Amazon do is count how many hard drives would need to simultaneously fail to lose data, calculate the odds of a hard drive losing data, and then multiplying. This gets you to 11 9's. In practice, this is almost certainly not going to be why you lose data. That will be because of a chain of human errors, or a code bug, or because the user accidentally deleted the data, or because earthquakes destroyed your data centers. I don't know anything about Wasabi other than what's on their web page, but I half suspect that what they did was look at Amazon's durability guarantee and then write that number down as their durability guarantee.
