No, in the movie all Harry knows is that Snape made an unbreakable vow to protect Draco. So when Snape gestures to Harry to keep quiet while he sneaks upstairs it would be natural to think he intended to save both Draco and Dumbledore from the other Death Eaters; that's what I would have thought was about to happen if I hadn't read the book. And even in the book all Harry knows is that Snape is to finish Draco's task if he fails; he figures that task must be something bad but he isn't sure exactly what it is.
