An important point here is that it isnt doing a 1-shot implementation, it is iteratively solving a problem over multiple iterations, with a closed feedback loop.

Create the right agentic feedback loop and a reasoning model can perform far better through iteration than its first 1-shot attempt.

This is very human. How much code can you reliable write without any feedback? Very little. We iterate, guided by feedback (compiler, linter, executing and exploring)
