I believe this verse is talking about not individual sins but "the sins" ie "all sins" ie salvation.
So if a diciple says, based on the Holy Spirit, "your sins are forgiven you" then all your sins are forgiven - not because the diciple said it but because the Holy Spirit completed the work and the diciple can see that.
Read Acts 8:9-24. The apostles were very careful in what they did and needed to see genuineness. The Apostle Peter told the man (Simon) to pray to God for forgiveness. Peter didn't forgive him, but God could.
