Where to cite has nothing to do with my original
argument (apart from
anything else citeing at the end only is largely meaningless since you
can't tell what is and isn't cited).
Your argument was that you had two sources which made it complicated
to show which statements came from which. That is entirely about where
to put the references. You can tell what is and what isn't cited by
reading the sources.
You gave two examples, in both of which you said you had the sources,
so why can't you cite them?
