For the Autofeather to happen certain conditions have to be met. Those conditions are there during the T/O, and during the APP, after an action that happens after putting the Gear Down. Other than that, the Autofeather will not happen automatically.

Correct !
It is worth noting that the feathering of the propeller does not shut down the engine. The engine can still be running with the propeller feathered.

About the Dash 8, don't know anything about it, but my understanding is that it has more power than the ATR.

It has been established that both engine propellers went into feather. We will have to wait to learn if that was caused by system malfunction, or if it was crew error when intending to reach for the Power Levers, or even for the Flap Lever, they instead reached for the Condition Levers.
