Difference in _parent and _self targets

Question

..

Answer 1

"_self Opens the linked document in the same frame as it was clicked (this is default)
_parent Opens the linked document in the parent frame"

It worked the same for both because the self was also the parent. Otherwise, _self would launch from that relative frame, whereas the _parent will always launch from the parent frame.

Answer 2

I am quite confused .. both seem to work as same
