Purling while knitting in the round?

When the pattern says to “knit 1, purl 1, knit 1, purl 1, etc”

Would you just purl like you normally would while knitting flatly, or would you do something different?

If you are doing a k1, p1 rib in the round, do just as you would do flat. knit 1, purl 1, knit 1, purl 1, etc. and on the next round, knit the knit stitches and purl the purl stitches, just as you would if it were flat knitting.
