If you were to block 20% and 10% in my hypothetical, with multiplicative stacking your mitigation is effectively 28%, so the net damage is 50.4%, bringing you to 49.6%, triggering Catharsis. With my earlier numbers, Catharsis heals ~12k out of 72k (~16.7% of Max HP), so your HP lands at 66.3%. If you time the same hit poorly as HoC currently is, with 15% mit and Catharsis triggering you'd still end up at 57.2%. The 30% mitigation is actually the weakest of these three scenarios. Similar to TBN's problem with %mitigation, HoC's maximum benefit only happens when you're guaranteed Catharsis will trigger. In the edge case where you're below 50% HP so Catharsis will trigger automatically and the heavy hit will be reduced by 30%, you'd probably just use Bolide instead.
