Right you are.
I'd add that, though this can be confusing, it does have a benefit.
A delimiter at the end allows an empty list of items to be distinct from a list of one item that is empty. That is, it allows empty items and an empty list to be represented.
If items are never empty, then the between-style will work.
If they can be, then the after-style might be better.
Revolution counts items (and lines) in a way that works for both situations.
Even so, a comma at the end does look silly.
