Moz doesn't just look at the text of a page, it also looks at the template and how "similar" it appears compared to other pages.

Here's a quote from Dr. Pete:

"Our system currently uses a threshold of 95% to determine whether content is duplicated. This is based on the source code (not the text copy), so the amount of actual duplicate content may vary depending on the code/content ratio."

Here are a few articles you can read to get a deeper understanding.
