No, the point is that he isn't just a monster foreign heel... it's that he is as close to the real deal as possible. Hell, the Ziggler story right now really isn't about Mother Russia or any other bullshit, it's about a lover scorned. If they do an angle where Rusev starts breaking guys ankles when he returns, it isn't about his heritage but how pissed he is that he was laid out. The foreign heel part is a bonus... it doesn't have to be his complete being.
