I think it is the latter. I think Paul is summarizing, and pointing to the wholistic salvation, which is eschatological Israel, ALL-ISRAEL. So, all who are (true) Israel, united to the Israel of God, the Israel of One even Jesus, will be saved--no doubt.
That makes Paul's statement a truism: all those who are going to be saved are going to be saved.
