i'm having a bit if trouble understanding row 4 of this pattern - how can you crochet into the row below when it doesn't exist - very confused! any help most appreciated!

With first color, chain 158.

Foundation Row: Single crochet (sc) in 2nd chain (ch) from hook and in each ch across -- 157 sc. Ch 1, turn.
Rows 1-3: Sc in first sc and in each sc across. Ch 1, turn. At end of Row 3, work color change in last sc as follows: insert hook in last stitch and draw up a loop, drop color in use and cut yarn leaving 6" tail, with next color, yarn over and draw through loops on hook. Ch 1, turn.
Row 4: Sc in first sc,* sc in next sc one row below, sc in next sc 2 rows below, sc in next sc 3 rows below, sc in next sc 2 rows below, sc in next sc one row below, sc in next sc. Repeat from * across. Ch 1, turn.
