Example 24 does indeed fit your print situation. You have BOTH regular text AND boxed material across facting pages. Look at the second part (2) of Rule 6 Section f on page 172. It refers to regular text with boxed or screen material on facing pages. I think you were looking at only the first part of this rule, which refers to the situation of ONLY boxed material across facing pages. Notice that the second part of this rule describes how to handle this material--regular print page numbering with a TN to explain the boxed material, just as the example shows.
