That would essentially be the difference, yes. Crepes are mostly the same general idea as pancakes without raising agents; this recipe doesn't contain baking powder because it hadn't been invented yet. Food evolution is quite interesting. Most recipes we consider traditional standardized maybe 50-100 years ago. A pretty good example of how far a recipe can evolve is how mincemeat pies evolved from containing mostly meat, some fruit, and spices in the 11th century, to the modern incarnation which has no meat and is just fruit and spices.
