The exact quote is “I communicated about classified material on a wholly separate system.” She clearly was referring to her personal system. Both FBI and DoS determined that she did not have a DoS e-mail address. If she did not have a DoS address and did not use her personal system, then what system did she use?

I think your video is very likely correct. I also think Clinton very directly lied straight to the face of the vet at the “Commander in Chief” forum, and by extension to everyone.
Asking her to explain what system she was referring to will cause your scenario to be validated. Either that or a previously undisclosed server will be revealed, which I think is exceedingly unlikely.
1) “I communicated about classified material on a wholly separate system.”
2) "I never sent nor received any material that was marked classified."
Both cannot be true. Which is the lie?
