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

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)
