Actually, it's the concept of 'save' that is unintuitive. The EPOC systems just kept your data, and it's one of the nice features that sublime gives you. In an ideal world, a document would keep its entire change history as a graph (not just a single line), and you wouldn't 'save' a copy, you'd name a particular revision of it so that it was easy to get back to later.
