The statement "There are words in the manuscript that only appear in a certain section" and the statement "common words can always be found in other sections" are directly contradictory.

Not to my understanding. Common words are common in both senses of the word 'common'. They are frequent and they appear throughout the text.
Subject-related words are usually not among the most frequent. This is why people analysing texts, and looking for changes (in subject matter or other areas) make an effort to remove such words if they can ("stop word removal").

While indeed I don't agree with all arguments of Montemurro and Zanette, it makes the text appear as if it is subject-matter related.
