The NTSB briefing seemed to posit two distinct accounts of the assumed feathering application.
The first, early in the resume, seemed to say that all communication and recording got lost two seconds after the feathering has been unlocked. Implying the possibility that feathering would have occurred two seconds later resulting in catastrophic failure.
The second account, during questioning, seemed to state that after unlocking, the feathering was (immediately?) activated, and two seconds later, all communication got lost, due to catastrophic failure.
Which of the accounts is the correct one?
