They measured a speedup. SIMD is a super common way to speed stuff up and good compilers do it automatically. A lot of string comparisons use SIMD now. In C++ if you use std:string on GCCit has done it for years. I bet Rust and Python (in the compiled runtime) ate doing it too. No sense leaving easy performance gains on the table.
