Seed Stitch edging - need to know what this is

Below are the instructions on a pattern im doing. Can anyone explain to me what Seed stitch edging means?

Row 1: (seed stitch edging) K1 P1 K1 P1, then K6 K2tog, (K9 K2tog)7 times, K6, (seed stitch edging) K1 P1 K1 P1.

Seed stitch is the K1, P1, K1, P1 pattern. So I understand that you follow this, then do the “K6, K2tog, (K9, K2tog) 7 times, K6”, and then you continue doing the seed stitch pattern again.
