If anyone has forgottenElena says that if they had met with Damon first, then maybe they would have all happened. Here we just show the scene from the past, where Damon first met Helen and inspires her to get what she wants, and, of course, forget about her meeting with him.
How do we know when you contact the vampire "drops" all suggestion and returns the memory of what had been erased. That is, at leastElena remembers a meeting with Damon (and his declaration of love in the 2nd season), and if the writers do not smoke, bamboo, it is possible that something else is very important that we did not show (unknown our previous suggestion of Stefan, Damon, Klaus, and so on, "that will change everything" - as they say in the synopsis to the series).
