It's telling you for this pattern
Row 1 (WS): K
Row 2: *K1, P1*
Row 3 (WS): K
Row 4: *P1, K1*
That the odd rows are the Wrong side of the work.
So Row 1 you will Knit the whole row
Then Row 2 you do K1, P1 the whole row
Then Row 3 you will knit the whole row
Then Row 4 you P1, K1 the whole row
Some patterns, it is quite easy to tell the "right side" vs the "wrong side"... for instance on stockinette where the knits are the right side whereas the purls are the wrong side; whereas reverse stockinette is purls on the right side, knits on the wrong side. Good luck!
