Once you charged, the opponent moves all his models into base contact, following the rules for that.
Piling in is basically the same move, but after the assault is resolved. If no one falls back and there are still survivors on both sides, you both move to base contact, starting with the player whose turn it is.
So... the answer is kinda both. Except the first time it's called Defender Reacts instead of Pile In.
