It can. My twins had less space than normal because scarring from abdominal surgery was deep (long scar, not laproscopic). I thought it was going to open up toward the end of the pregnancy...it was looking very stretched thin. I did not have that nice basketball belly, but looked kind of lopsided because they couldn't stretch to the lower right side of my belly.
