I think a it could be couple of things.

A. At the time the pitcher made the play (which is where it counts from as far as the base runner goes) the base runner was between second and first there for he was going to second at the time of the throw so when the ball went dead he got the base he was going to and the next one.

B. You didn’t say that the ball went dead if it didn't then he could run home if he likes. I had a play similar to that the other day the ball bounced off the pole 2 feet from the edge of the fence therefore it was still live and the right fielder attempted to gun the runner down at home but the catcher didn’t make the tag.

C. Something else that I’m not thinking
