It is not completely wrong. At Madame Malkins Malfoy did not introduce himself, and I think he did not realize that Harry was Harry. In the train he came to Harry's and Ron's compartment to see if there is really "the Harry Potter" in there. Then he first introduced Crabbe and Goyle and them himself as Draco Malfoy. And until that moment he is just described as "the pale boy. His name is not mentioned until Hogwarts Express.
