In that example it's not any sort of special thing. You just literally feed the entire contents of the query (everything between the parens) into the parser and see if there are any parsing errors. That's just fine! No special-casing required, just possibly adding a mode to your existing parser to flag parsing errors rather than just silently dropping them.
This is very distinct from a special-case syntax for testing rule nesting.
