Contradictory or Unified Signs? (Colossians 2:11,12)

The Apostle Paul mentions baptism and circumcision as two signs of Christ’s work. Does Paul mention circumcision first to show that there is something more basic or inferior to this sign tied strictly to the Old Testament? Does he mention baptism second to communicate we have really arrived in history? Is it possible that Paul sees these two signs as having similar implications, but looking to the coming of Christ from different viewpoints in history?
