Thanks for the PR. This is select_biased, so res == 12 is indeed redundant and only res == 63 is fine. I think using res == 13 like this PR is not a good idea because it makes it impossible to tell from the example the difference from a normal select.

Good point, I changed it to assert_eq!(res, 63) to make it clearer
