What is the salient difference between those two? I don't see the point
of the distinction.

Why have you chosen an analogy – CPU registers – that still uses the
misleading “copies in containers” model, rather than the “sticky-notes
on objects” model? The latter more accurately describes Python's
references.

This is quite false. Every object in Python is typed and structured, and
to the extent that Python has “variables”, they always refer to a typed
and structured object.
