Sure, but it did better on the test, which matches OpenAI's claim. More bang for more buck.

Interestingly, using your tests as a comparison, 5.5 low beats 5.4 medium at a 82% of the cost.[0]

5.5 is definitely smarter indeed.

And yes, 5.5 low seems to be as good as 5.4 medium, but a lot cheaper. In my experience that also holds up in real-life n8n agentic usage, so using 5.5 low is the best way to go atm.
