I got bored, here's some proof.. the red circles indicate tiling that the shallow water/dirt path generator cannot do.. unless someone made a different version that CAN do this.. which I have yet to see.

Green circle indicates a tile error, that the generator would not make.

However, this doesn't rule out the possibility that he used generator in the level. It's just pointing out some of the reasons that he might not have.
