Translating Revenue if hyperinflation is present

I was under the impression Revenue always has to be translated under the average exchange rate, whether current or temporal method is used.

However in Reading 15 of FRA Question 30 in the CFAI text, after adjusting the amount of revenue in the local (and functional) currency for hyperinflation, it is then translated to the parent’s presentation currency at the current rate. How come Revenue is translated at the current rate here and not the average rate?
