It is a little far out. The templates extend from -70 to +72 mm left to right, with the most extreme structures as the left and right middle temporal gyri. It's hard to say why the publication would show that without more details, but some guesses include group variability that extends to those areas, heavy blurring and draining vessels. See this very recent post (today!) for more info:

Generally, we don't recommend alignment of EPI data to an EPI template. Instead we align using the subject's anatomical data and anatomical T1/T2 templates.
