Let's talk electrical active vs dsp active xovers

Ok, so this one has been bothering me for a bit now. As many of us, most crossover slopes cause phase shifts across their affected areas in both passive and active crossovers. We also know that higher order (i.e. LR24) crossovers will start rolling off BEFORE the calculated frequencies. (-6db at xover point for LR24)

Do the dsp algorithms simulate this? Or are they superior in giving in-phase and proper rolloff characteristics? Are all dsp crossovers much the same in the way they work? This interests me, does anybody know about it? Or if there's any easy to access info availa know ble on the topic?
