The "limit payment possibilities" means that, f.e., Apple cannot stop a banking app from using the on-device secure enclave and the NFC functionality from making payments available if Apple also offers a payment service using those functions (or to say it differently; If Google or Apple make a payments app, they must allow everyone to develop their own payment apps for their ecosystems and make all functions available that are necessary to have all functionality of Google or Apple's own apps).
