What last 4 rows?

I am knitting my first sweater. I am so close to finishing the front piece. Please check out the Favecraft web site and look at the bamboo knit top pattern. I have knitted very successfully up to the ending of the “front” pattern where it says “Work 3 even rows” I am not sure about the next step it says to “Rep last 4 rows” I am not sure what last 4 rows it means. Could anyone shed some light on this next step?

Thank you,

That means the previous 4 rows - you did one row with an inc or dec in it, then 3 rows plain. That’s the 4 rows you repeat.
