Yes. It's commonly called receding. Ice flow is always away from the high areas, so toward the margin. When the ice sheet mass is out of balance (total melt exceeds snowfall), then the ice sheet recedes. Even if the ice sheet is receding, flow is to the margin.
NB: flow is not always to the south. It is always down the potential, so "downhill." In Maine, that trend is to the southeast.
