im not sure without seeing the full directions, but it does sound as if it wants you to start working flat rather than in the round.
This is indicated by the fact that you have to turn your work (thus breaking the circular) an the fact that it starts referring to it as rows rather than rounds.
When it tells you to turn, litterally turn your work and work backl the way you have just come, at the end of that (when you get back to what would have been the start/end of the round) turn and go back again doing another row. You are now working back and forth in flat stockinette so make sure you are now alternating knit and purl rows.
