Not at all, the expansion will take longer for some guys to keep but the fact remain, if you push your tissue beyond it's limits it has no choice but to remain deformed permanently eventually. I guess the point I am trying to make can best be exemplified by ear augmentation through larger jewelry. With each increase, over time, the tissue ever expands. The penis has much in common with this as there are no bones present. This means we are dealing strictly with skin and tissue which is, by most standards, easy to augment. I am surprised balloon expansion has not been suggested by the phalioplasy surgeons yet.
