Does not work as there would be many of the same patterns with the above for loop as inverted_tcc_comparison and inverted_tcc_comparison_with_nans have a non empty intersection. The reason why it worked for the other usage of inverted_tcc_comparison/inverted_tcc_comparison_with_nans is because it was the resulting pattern rather than the matching pattern.
