To repeat what was said above, accuracy is not the same as engine correlation.
Engines often play moves that are counterintuitive and weird, but nonetheless good. This is because they can evaluate large trees of tactics in a way that humans cannot.
If a human finds a natural move that is just as good as the engine move (in terms of evaluation), they are still playing accurately, but they are uncorrelated with the engine. Playing accurately is not a sign of cheating. Playing many engine moves is a sign of cheating.
