Would the worms remember without this “refresher course”?

So, no. But they do better with the refresher course than other worms if I understand correctly.
AKA - there's no effect as far as we can tell without further experiment.
Correction: the paper (http://jeb.biologists.org/content/early/2013/06/27/jeb.08780...) is talking about the worms before re-familiarisation. They claim significance for previously "trained" worms being faster at picking up the training post decap+regen.
