That does not change $_.

That does not change $_ either; /c complements the search class, so the
first translation counts the occurences of non-letter characters, and the
second translation counts the occurences of non-digit characters.
When the replacement class is empty, and /d is not specified, then the
search class is used as the replacement class as well.
