Double Seed Stitch--Flat vs. In The Round?

[IndyPurl]

Directions I am finding for Double Seed Stitch are as follows:

(K2, P2) two rows
(P2,K2) two rows

I want to knit an earflap hat in this stitch. The hat would be worked in the round but the ear covers need to be knitted flat. Kind of like this knitter did: Earflap Hat

In this pattern for a hat and blanket the pattern states:
In the Round (hat):
Rounds 1 & 2: K2, P2
Rounds 3 & 4: P2, K2

Flat (blanket):
(K2, P2) two rows
(P2,K2) two rows

These are identical (aren't they ) and if so, is this accurate that I will get the same look flat or round by continuing with 2 rows of *k2 p2* then 2 rows of *p2 k2* regardless of whether or not I am knitting flat or in a tube?

Or am I really confused?

Thanks in advance to anyone that can clarify!!!

PS- Is Not critical --is Double Seed the same as Double Moss or is there a difference?

Yes, the pattern would be the same whether worked flat or in the round, as long as you have a multiple of 4 sts. Seed and moss and their doubles can be different depending on the country of origin of the pattern; here's the difference -

UK seed stitch is a stockinette background with an occasional purl stitch
US seed stitch is alternating knits and purls across the row and up the columns
UK moss stitch is the same as US seed stitch
US moss stitch is alternating knits and purls across the row for two rows, and then alternating purls and knits for two rows.
UK double moss stitch is the same as US moss stitch
US double moss stitch is two knits alternating with two purls across the row and up the columns
UK box stitch is the same as US double moss stitch
