Load pull analysis is just an empirical way to find the optimum load impedance depending on your performance criteria. Depending on if you're optimizing for power transfer, efficiency, emissions, linearity you can map contours to determine the best trade off. It can also be used to characterize an amp's performance under adverse load conditions (e.g. detuned antenna).
