Long single crochet around dcs just made

Afghan Pattern says : skip next sc, dc in next 3 sc,work LSC.
Afghan stitch guide describes Long Single Crochet (LSC): Working AROUND last 3 dc made, insert hook in skipped sc, YO and pull up a loop even with last st made, YO and draw through both loops on hook.
I can't figure out one goes AROUND stitches already made to make the LSC in the skipped sc and then continues on
back in the original direction
