What to make of current Israeli policy regarding settlement construction?

On the one hand, we have Ehud Olmert's solemn commitment at Annapolis: No new settlements, no settlement expansion. And on that same hand, more or less (perhaps minus one or two fingers), we have the PM's explicit letter Of December 31, instructing the ministers of defense, housing and agriculture to refrain from authorizing any construction in the West Bank without his and Defense Minister Ehud Barak's prior approval. Specifically, "construction, new building, expansion, preparation of plans, publication of residency tenders and confiscation of land stemming from other settlement activities in the (West Bank) area will not go forward and will not be implemented without requesting and receiving in advance approval by the defense minister and the prime minister."

Clear, yes? Unambiguous, yes?
