No. Not John's. It was a reference to the NT water baptism in the name of Jesus for remission of sin instituted and required of all after Jesus' sacrifice. (Luke 24:47, Acts 2:38, etc.)
The Acts 19 account indicates the 12 were rebaptized in water in the name of Jesus. We know it was water baptism because the record specifically mentions that afterward Paul laid hands on them and at that point they received the Holy Ghost. Also, other scriptures reveal that baptism in the name of Jesus is water baptism. (Acts 2:38-41, 8:12-18, 10:43-48, 22:16)
