Most of this isn't that damning. SOC IIs are already highly templatized, so pages matching up really isn't meaningful. In fact, an overly detailed or overly verbose template is more likely to have matching pages since you'd never have to add additional content to it.

System descriptions don't necessarily hold much weight. They're often more about giving a general shape of the system to help orient the reader, rather than providing a technically complete picture.

Most of the meat in these is about the controls being tested (which are semi-standardized within an auditor) and the results. Many of these controls are really basic and easy to get "no exceptions noted".

That being said, nearly everyone has at least one exception, even if it's minor. The fact that they didn't find any across all of their clients is a strong indicator they're not diving deeply enough.
