Assuming it wasn't just luck, it seems impressive they managed to maximize their (landing attempts/fuel reserves) ratio like that.

It is a requirement [1] to land with 45 minutes of fuel remaining, if the pilots go under that, it is considered an incident. As soon as estimated landing fuel goes under the limit, the flight needs to declare an emergency (as was done in this case).

Exactly. This will have a lot of consequences.
They got within a hair of crashing, there is nothing impressive about this. 30 minutes, ok, you still get written up but this is cutting it way too fine.
> this is cutting it way too fine.
Either this is true, or this is why there’s a 45 minute reserve requirement. There were three failed landing attempts in two airports prior to the successful landing, and they spent almost as much time attempting to land as the scheduled flight took.
Seems like this was exactly the scenario it was designed for?
No, this is what should never happen. I wrote fuel estimation software for cargo 747's and the one thing I would have never ever wanted to read is that an airliner of the company I worked for had landed with too little fuel.

I would imagine 6 min fuel left was designed for something extreme. Maybe involving damage to aircraft limiting where it can land etc. Or extreme weather event such had high winds affecting all airports within 500 miles.
