> What part of this process makes the s3 webpage rank up in search algorithms though?

No idea. The article basically ends with "I'm not sure exactly how this happened so I'm going to talk to some experts". A bit of a letdown, tbh. I was waiting for the big reveal!

I'm not sure either but it looks something to do with domain authority as the pages are hosted on amazon s3 and the domain is related to amazon maybe it makes Googlebot think the pages are affiliated to amazon so it ranks them higher (just like articles on wikipedia.org rank higher with less effort). This is all conjecture though because I'm not an expert so maybe somebody can correct me or add to it.
