More than half that distance, but maybe not in that direction? I don't know, that's just what Wikipedia said. Alpha Centauri A and B are each roughly the mass of our sun, so together they should have more pull. Yes, this stuff is continuous (but gets very sparse), and there must be some region where it's temporarily balanced between the stars. It's all quite variable as stars move relative to each other, and the stuff can be taken for a ride on a new star.
