Problem with Lion Brand Homespun Crochet Ruffle Scarf Pattern

I am an intermediate crocheter, but have not been actively crocheting for quite some time and would like to get back into it. I recently found a pattern on the Lion Brand website for a Crocheted Ruffle Scarf, which I thought would be a good way to get started again. I printed the pattern, however, I am unsure where to proceed after Row 4. It doesn't say whether I continue with Row 4 until I reach the length and then fasten off or whether I repeat Rows 1-4 until I reach the length and then fasten off?? The pattern is labeled as easy, and maybe I am just reading into this too much??!! Please help. Thank you.
