How did AILabs Team get such performance in the superglue benchmark?

If we look at superglue (https://super.gluebenchmark.com/leaderboard) benchmark leaderboard, it may seem that AILabs does not perform super well. But if we look at the model card (https://super.gluebenchmark.com/submission/PM5gv5ownvaXy1JhZNCi7nvkgDR2/-MVAj4j69EIbw0Y1XqY4 - broadcoverege) it appears that this model performs surprisingly well! How is it possible? Where can aI find the description of their method?
