It’s definitely there from one angle. It’s the right engine, which is the one that is shown having a compressor stall earlier. It’s quite possible for a jet engine, to run, but not produce power, or to start compressor stalling as you increase the power. But, if running, even at low power, you’d expect the associated generator to be powered as well.
If I had to make a guess (and that’s all it is), I’d say that they had limited power from some time after the go around started. Not enough to just fly around, but enough to extend the descent appreciably. That makes explaining the speed on finals easier, but also would have made any decision to head for the water easier too. The lack of electrics remains confusing.
If you had one engine shut down, the other would need to be producing around 75% power for a normal single engined approach. But if your running engine starts stalling at 65%, you have a shortfall that you can’t make up, and that probably leads you to the configuration that we saw.
