That's because the higher octane is harder to ignite. The issue of unburned fuel is still there, it's just that the higher octane masks it because it's not as sensitive to the heat in the combustion chamber.
Hence the reason why higher octane cures detonation, as well as heat soak and vapor lock, and generally also requires more ignition lead for best performance. It's slow burning.
