I think that probably means about to maintain. The BMR calculators aren't always that accurate though. I would say its best to perhaps start with that and see your rate of loss and if it's too much, add a couple hundred calories in, and if you're not losing, drop a couple hundred. It could take a little bit to get on track how you want to be, but then as you lose it is also going to change constantly.
I'm no expert on the science of it though.

Perhaps someone else can give more insight.
