As I said, for APT, the order has meaning _always_.
apt-get install foo bar
Is completely different of
apt-get install bar foo
Could you please elaborate on this? I know for sure that Pre-Depends exists
just for the cases where order _does_ matter. But I've never had problems
in
installing packages in any order (or probably I've just been lucky).

I'm not sure, but I think the follwing indicates the problem.
Imagine that you have none of {foo, bar, baz, qux} installed.
Foo has "Depends: baz|qux"
and Bar has "Depends: qux|baz"
My understanding is that in that case
apt-get install foo bar
installs {foo, bar, baz} but
apt-get install bar foo
installs {foo, bar, qux}.
This is not always a major problem, and in most cases the end user will not
notice
it, but under rare cases it is theoetically possible that the dependency
chain with conflicts could cause problems. (At least it seems like that
might be the case)
