Why does Raymond Queneau include variations containing unintelligible words and phrases, such as in the "Permutations" variations?

Raymond Queneau includes variations containing unintelligible words and phrases, such as in the "Permutations" variations because Exercises in Style is more than an experiment in the retelling of a basic story. Exercises in Style is also an experiment in language, and an experiment in writing. The unintelligible variations are included to show Queneau's experimentation with language and writing.
