I have always understood "lessons learned" to be last,
I might suggest that you submit an Errata to (ISC)2. By submitting the errata, you would be asking them to review the materials and hopefully they come back with an answer on their logic.
@CBMExamTeam I know that your team does not develop the training material but am not sure who else to tag on this one.
The exam is not intended to trick people, so I would answer the question with what I believed to be the correct answer.
