I am doing thissweater, but I got stuck at a point. Please convince me that the pattern is correct so I can go on. Read the Left Front part:

Next row (RS): Ssk (pocket edge), work to end of row. Next row (WS): Work to last 2 sts, p2tog. Rep last 2 rows until 12 sts have been dec’d, ending with a RS row

How could you start with a RS row, dec each row by 1 st till total of 12 sts, and end with a RS row again?
