Yeah, that's exactly how I understood it. Definitely not paralyzed even briefly. Miserable sequence of events:
Tartarian Cyclops and two Devil-killing Harbingers cloud trapeze on top of devil.
-- Battle starts --
- Devil flies in and sends a fully kitted Harbinger to Inferno
- Tartarian Cyclops casts Petrify
- Second Harbinger casts Mistform
- Devil sends Cyclops to Inferno
- Second Harbinger flees
