I want to say that is technically incorrect.

Surprisingly, the original 1908 paper introduced
a union that simply takes a union across the
elements of the set.

That is, a union consists of the elements of
the elements of the given set.

I say surprisingly because Zermelo admitted
objects different from sets in the description
of his domain. That definition of union would
mean that two sets could have the same union
if they contained the same sets but different
urelements.

Of course, the axiom of union is forced to
take that form. What I mean is that it may
be interpreted as "closure under arbitrary
union" where arbitrary applies to whatever
exists in some given model.

It is just that one becomes so used to
thinking in terms of pure sets.

And, naturally, your mention here applies
to casual usage just as we do not write
proofs in formal derivations.
