You're not too wrong - what we call seed st is called moss stitch in the UK. 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
