It's the difference between what bash reads and its translation to an internal
form based on words.  The words are then translated to an external form
with quoting added to make the original and external forms behave identically.

But at that point, the quotes have been discarded.  You're talking about
the words after all the expansions, including quote removal, have been
performed.

While it may not be identical in appearance, it's identical in behavior
and effect.  If it's not, that's a bug, and you'd notice it.
