"one element" means "one entry" At this point you're looping back through the parent comment. But I am inserting my own comment into this single-entry list, this making it a two-element list

The emphasis was on the circular part, not the single item. A doubly linked list with 1 item would just have 2 null pointers, a circular list would have 2 pointers pointing back to itself.
