Knit into that leftover stitch but leave it on the needle and put the new st on the L needle too. Then do 2 more and you have 3 new sts over the gap where you bound off the others. Put the needle back to your right hand and finish working the round. You don't need to make any changes, because there is no 'american' style of knitting. US and Canadian knitters use english, continental, combined and several other styles.
