Catalytic converter failure on ML

Got an ML350 in the shop with the infamous check engine light because of catalytic converter fault code. All four (upstream and downstream) O2 sensors are swinging to beat the band. On healthy ones I've watched the downstream signal is steady. Is the fact that all four swinging a sure thing that the cats are bad?
