Did you try it? Because that's not what it does. submatch(0) expands to the first submatch, which is the entire thing that's matched, and +1 adds 1 to this, which will a;ways result in "1" here since any string that doesn't start with a digit will be type-coerced to 0.
Anyway, /n being intended sounds likely; I forgot that would report the number of matches. Still very odd how that got morphed to what's in the article.
Others have commented on built-in vim functionality for counting words, but assuming the author copy-pasted a similar looking command, they may have intended something like:
Knowing that the n flag will return a count instead of doing the substitute may be useful to know, but I personally don't need a search count very often.Knowing that you can execute a vimscript expression on each search match using \= is also cool and I was unaware of such functionality. https://vimhelp.org/change.txt.html#sub-replace-expression
