Something about repeating those five words that nobody above has emphasized:
You’re given the five words, asked to repeat them immediately, and not warned that you will be asked again later. Then, in between the first time you’re asked to repeat them and the second time, there are several other questions that require your full attention.
I think the problem to count down from 100 by sevens is there. You need to fully concentrate on that to do it. I think there’s also the question in there where you are read a full sentence and have to repeat it.
You have no chance to rehearse the five words silently in your mind while you’re distracted with those other questions, and you’re not given any reason to think you should anyway.
I don’t know if I could repeat the five words after all that distraction.
