AAO Positive Response for I290B Appeal?

Hello, I just received my AAO letter for an appeal.I have 2 criteria met and AAO agreed with me that I should also be considerably have met the other 2 criteria. Their final order was "The Director's decision is withdrawn. The matter is remanded for the entry of a new decision consistent with the foregoing analysis." If the service center approves what the AAO think for the other two criteria, they can proceed to final merits of determination right?What does this mean tho? and should I hope for an approval stil?Thank you everyone.
