This just does not make sense to me

I need help with this line of a pattern

Change to circular needle. Place marker. Knit to end of row. Cast on 196 stitches. Join being careful not to twist knitting.

This is from a free pattern on the loin brand site. Pattern number BK4K-0702003.

Help Please


you knit one wide side of the bag, flat knitting; then you knit the narrow sides, bottom and handle in the round; bind off, and knit the other wide side of the bag flat.
