It means to work the stitches into the stitch on the left tip.
In this case, knit the stitch as normal, but dont slide it off. Bring the yarn to the front between the two tips and then knit into that same stitch again and slide it off. You'll have 3 where there was 1.

Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
