That is indeed an interesting point.
The grace alone through faith camp always uses "alone" to try and refute the need for a total permanent repentance from sin and baptism in Jesus' name for the remission of past sins; much less enduring till the end..."for salvation".
The "alone" camp believes that salvation is assured instantly, well before the final judgement, so nothing they do "as a Christian" matters as an impediment to salvation.
They have no part in salvation, and have left everything in God's hands.
They are in for a rude awakening.
