I think it all depends on what your attitude is when you get to goal, or near it. If it's "yay I can eat again" and you dont then follow a maintenance plan and change your the eating habits that got you to put on the weight in the first place, then of course you'll put it back on. I did LL, lost 5 stone and put back 7 stone. I didnt really regulate my eating habits for long, I did initally but then got bored of having to think about it all the time and went back to eating what was frankly crap, ready meals and stuff like that, so no wonder the weight went back on. I haven't really considered how I'm going to deal with food when I'm back on it as it's so far away but I do think the key for me is low carb, I find carbs addictive and last time I remember that once I'd had carbs again I felt out of control.
