It's not just the binge. The insulin response would store any fat you've eaten that day. There would also a drop in your gluclose as the insulin compensated, leaving you weak, hungey and feeling blah. Cholesterol and other health issues you worked hard on balancing would also get out of whack.

A one time bite of a candy bar probably wouldn't do all this, but if you are consistantly eating them, then yes. The regular candy bar would stall you far more then the LC one.

When you hit maintanance it is ok to rarely have a higher GI treat. What you need to do though is rea dup on the Glycemic index and the difference between carbs. Get Atkins for life since you are so close to goal. He has easy to read tables tha tlist foods to eat often, in moderation and rarely. He also discusses the glycemic index more if I remember.

You could also look into CAD fo rmaintaining, which would allow you a little more freedom during your reward meal. The rest of the plan is much more strict and difficult then atkins though and again you have ot read the book first.
