Knit three rounds even?

finishing the toe of a sock. After doing the decrease round it says, knit three rounds even. Does that mean three more rows of This repeats after each row, sometimes it says knit one row even, so it ends up being about 20+ rows to finish the toe, after kntting the decrease rows for row 13. Can you help me please!

To knit even means to knit in the pattern (stockinette st in this case) without doing increases or decreases.
