Every time I tried it, it didn't work.
It certainly changed a lot on those years, but the reason nobody acknowledges it is probably because it's a coin-toss if Google wants "verbatim" to mean verbatim today.
Quotes actually stopped working (they became a hint, instead of filtering the results) a long time ago, and many people insisted for years that the verbatim search worked. Probably because those tried it on the days when Google decided to use a standard dictionary. Nowadays even those people gave-up.
