I guess I didn't address your question directly;
My thoughts are that yes, eventually both will be above the current price of Ƀ right now. It may take a while to get there, but I think both will eventually climb.
But, to answer your question more directly, it may currently be more like what you say, where one's value is directly correlated to the other, and BCC "taking price" from BTC.
I think over time the effect of this will subside and we will eventually see both on the rise.
