There hasn't been two articles under the new study design as of yet (except for those comments in 2011 but I hardly count that). I assume the reason behind this is because with the context section now, there just simply isn't enough time. Before context was there, the persuasive writing piece was meant to be quite short, meaning you had more time to deal with 2 articles in language analysis. With context now there, having two articles is less likely. However, I wouldn't completely rule it out and you should at least have a rough idea of how to deal with multiple articles. Ultimately it's more of a case of being strategically and mentally prepared for what to do. It's not something you have to suddenly go out and specifically prepare for since the underlying fundamentals are still the same as a single article analysis.
