Otherwise the core can stay in the pump chuck with you unthread the chuck from the wheel.
As happened to me one time. You take the tire off, change the tube, struggle to get the tire back on the tube without pinch flatting (this was a road bike with deep rims and a tight tire), pump the damn thing up to 100psi and psssssssssss. All the air goes out as you remove the pump and you feel like you're back (almost) at square one. Horrible.
