"As Set" meaning

Knitting a sweater with a cable pattern. Only the right side rows are on the diagram. Instructed to knit return pattern “as set”.
Any ideas on what this means?

knit the knits, and purl the purls.

Assuming the cables are knit set on a background of purls, as you’re working across the back you will see the back of the purls (which now look like knits) so knit those. When you get to the cable sections, you’ll see purl stitches (the backs of the knits) so purl them.

Thanks so much for your information. Now it makes more sense to me.
