Reply to VCI filter knob under 1.3 firmware?

I'm just wondering why the 1.3 firmware turns the filter knob into a double knob, where middle to far right is 0-127 and middle to far left is 0-127. Before upgrading, I assumed moving the knob to the far left or right would turn off the filter, because the overlay says "cut". But obviously that is not a feature and not possible I believe without Bomes. I feel like there is some added functionality to this filter knob that I'm missing.
