It implies no such thing. It says "tuples may be nested" but fails to
show an example of a nested tuple on the LHS of an assignment. I don't
see how you can draw the conclusion from this that it's not supported.

You can't very well demand that a tutorial have examples of every
feature. Perhaps (continuing the sarcasm for a bit) you also didn't
think that tuples could be nested more than one level, since there is
no example of that? Plus, you could have tried this in the interactive
interpreter in 10 seconds rather than spawning a long thread.
