He seems to have edited his comment because the part you’re replying to isn’t there any more, but you’re correct, open offices don’t improve communication and they can’t meaningfully improve communication. If you happen to need to “communicate” with any of the maximum four people you’re physically adjacent to, then yes, you can start a conversation without having to get up from your chair. Otherwise, you have to get up and walk across the room to where the other person is (or just IM them): exactly the same as with cubicles.
