Obama has been pretending that Israel is the party that has been refusing to negotiate or make concessions (I guess that means we are being Alinsky-ed). Now he's demanding that the Israeli gov't form a detailed written summary of its negotiating position, which the US will present to the PA and the Arab League for review.
What comes after that is not clear, but probably a multilateral bludgeoning for concessions - including concessions on the refugee issue. All the while Abbas can sit back and enjoy some photo ops and have Obama do the work for him. No need for him to negotiate, make concessions, or commit to peace and coexistence.
