The top comment does explain that because of this agreement between goodco and badco, goodco isn't actually shielded from the liability, because it still has to reimburse for the liabilities now owned by badco. If that's actually honored it doesn't seem like a bad thing at least (now it might be enabling more legal skulduggery later down the road, so it's reasonable to be suspicious, but the actions so far don't seem as nefarious as the plain texas-two-step where the two wind up completely split).
