Of course it doesn't bind people who haven't ratified it yet. Rather, that clause is to make clear that the agreement will become binding for those who have ratified it once 85% have ratified (preventing a holdout from slowing down the majority). Notably, a similar protocol was used for the adoption of the US Constitution (see Article VII).
