I think you may have inadvertently put your finger on it. This is how Draco returns.
I really wish that were so, but it just doesn't make much sense to me. Draco left because of both politics and security concerns; while Hermione's death may make the politics a little bit easier, the first death at Hogwarts in fifty years isn't going to soothe Lucius' nerves any.
I suppose that sending Draco back to Hogwarts might be a way for Lucius to signal that he was behind the attack on Hermione, but I think Lucius cares about Draco's safety rather more than signaling. He also has many other, less dangerous ways to signal that; I wouldn't be surprised if he forgave Harry's debt, for instance.
