No, they return the correct tuple.

However, "ZPublisher.HTTPResponse.setBody" does special things with some
special return values. Most prominently:

  *  an Python false value is translated into an empty
     response. This leads many browsers to wait forever...

  *  a pair is interpreted as "title,body".

     That's your case. When you look at the HTML source, you
     will see your first element wrapped in a <title> and
     your second element in a <body> tag.
