I don’t really see how a near infinite corpus which occasionally contains that pattern could end up with it so highly represented in the output.

I could see this being an argument for why it ends up being bland or having an inconsistent style (for example).

So I suppose that could be a theory, that what happens naturally has a structure that needs to be corrected for, and right now the mechanism that produces the structural correction is overly simplistic and heavily overweights examples of that structure, but that this structure does not actually occur naturally from the model.
