Yeah, that's what CRF does compared to CQ mode. It lowers the quantizers in high motion scenes, so these don't eat as many bits as they would with a constant quantizer.
This is okay, because in high motion scenes we can usually deal with higher quantizers, as the loss is less visible. So CRF is a more bitrate-efficient version of CQ.

But 2-Pass will actually move bits towards the high motion scenes, compared to a 1-Pass ABR encode. The latter would blindly give all scenes the same bitrate (more or less).
