you'll be doing just that, binding off a few stitches (however many the pattern specifies) at the beginning of the row, and then after that knitting as per your pattern. so, you'll knit or purl the first stitch, knit or purl the 2nd stitch, pass the 1st stitch over the 2nd, etc, until you've bound off the right number for you.
a discussion about this was on knitting help a while ago and came up in a google search: http://www.knittinghelp.com/forum/showthread.php?t=90500
binding off 'in pattern' just means you're either knitting or purling each stitch as needed, and then still following the 1st-over-2nd method.
ETA - if you're super new to knitting, so binding off is a new concept, KH has great videos on how to do it at http://www.knittinghelp.com/videos/binding-off
