A first sleeve is shifted with a ball landed on a seat to open treating ports. At the conclusion of the treating such as fracturing, another ball is dropped on a seat in an adjacent sleeve. The adjacent sleeve shifts to contact the initial sleeve that was shifted earlier. When the sleeves abut the treating ports are closed by the second sleeve and the production ports that are preferably screened are also opened by the shifting of the second sleeve against the first sleeve. The first sleeve hits a travel stop in the housing to produce the full open position for the treating ports. The balls can be progressively larger in a bottom up direction for the procedure or the balls can all be the same size as the landing of a ball on the first sleeve reconfigures the sleeve above for the same sized ball.
