It's testing that the `omp parallel num_threads(3)` a few lines above doesn't apply to the `omp parallel` below. If the number of available threads is 3, then `omp parallel` is going to start 3 threads by itself, not because of leakage from `omp parallel num_threads(3)` and the test will incorrectly fail.
