Yea, it didn't mean that UBI could replace all of social security for everybody. Social security is (greatly simplified) made up of a guaranteed minimum payment + a payment you've 'earned' by working. UBI would replace (and be equal to) the minimum payment, the money that you've 'earned' from working will still be paid out. The core point is that at least a chunk of UBI will be replacing existing government subsidies and not be in addition to them.
