This is exactly the tricky issue the article is trying to explain: you should not be fooled by someone giving you separate R values for different groups in the population and, if they are all less than 1, claiming the epidemic is now under control. It may make sense to consider the R values for different sections of the population, but care must be taken when combining them. The examples are correct, as you can see with some very basic maths.
