It seems like the cascaded biquad doesn't work in the trivial case when DBS is set to 1. This is useful for filters where the centre frequency changes with constant amplitude. Those are implemented by pregenerating coefficients or generating them on the fly. The cascaded biquad then operates with constant amplitude.
