Not sure what you mean here.

So is it now wrong in your opinion or not?

The example text says (there is actually a typo, fixed):

   To following tuple expression can be used to find all good people

       // person -- // evildoer

If it says "tuple expression", then maybe then this is what is meant
:-) In contrast, the example above says "query expression".
