That comment is very sneaky. They say that they aren’t going into predicate logic (ignoring spelling out universal quantification), but understanding the analogy of addition to logical and is a pretty fundamental insight you learn from predicate logic.
The real difficulty here is natural language. When we have built-ins in Python (or other programming languages) that try to be too much like English, I think we get tricked into trying to read them like natural language (or at least this is a pitfall that beginners can fall into easily). all and any are logical quantifiers, and they behave differently than “all” and “any” in English.
