Yes, that's the intended meaning. Which is why it should not
mention Lisp symbols, which are something else again.

I don't think any example is needed. Essentially we are saying
here that if a letter has word syntax and `-' has symbol syntax
then \"\\\\sw\" matches a word char and \"\\\\sw\\\\|\\\\s_\"
matches a word char or a symbol char. Not worth saying, IMO.
