 Typesetters are right about their rule because often their text is set in a narrow column where those rivers might appear.  A brief has an unbroken 6.5 inch span of text on each line.  The rule for typewriting class makes sense in its context, too.  No one anticipated Internet text boxes.  Good thing they invented find-and-replace 15 years before they invented AOL.
