It could be a joke or a leftover from a previous example where the OP
used three different things, such as to_upper, to_lower and trim, just
to change them at the latest moment.
But it might be not: the question of what the result of
to_upper(to_lower(to_upper(rng))) is supposed to be is not trivial at
all.
