If a sentence has multiple "valid" interpretations, then it doesn't matter what the "correct" interpretation is. If someone says that a sentence is confusing or hard to read, you 100% must believe them and fix it. Dismissing concerns about clarity and ambiguity as merely "pedantic" is one reason why people fail to develop written communication skills. I have been burned many, many times in my career by making charitable assumptions about another engineer's ambiguous language, only to realize much later, after significant cost has been paid, that they had a completely different (and often wrong) idea.
Teaching people to be better writers is a hill I will gladly die on. I don't care if you defend your point or not, just read my comment and try to understand why someone would care deeply about this sort of thing.
