Surely they would be testing the configuration(s) that they use in production? They’re not running RDS without hugepages turned on, right?

I'd guess they have dozens of people across say a Linux kernel team, a Graviton hardware integration team, an EC2 team, and a Amazon RDS for PostgreSQL team who might at one point or another run a benchmark like this. They probably coordinate to an extent, but not so much that only one person would ever run this test. So yes it is duplicative. And they're likely intending to test the configurations they use in production, yes, but people just make mistakes.
