If IS is off, there should be no need to recenter the sensor after exposure. And such recentering wouldn't require anywhere nearly that much time.

How could we know that? I'm afraid we know close to nothing about the algorithms of IS and the logic behind them. I don't find it impossible that there's a sequence of sensor movements after each shot to confirm its position and recenter.

Nothing is impossible. But I don't find it likely, first for the reason I already mentioned (there is no reason to recenter a sensor that must already be centered when IBIS is off), second because the IBIS mechanism must work much-much faster than this, and third because recentering the sensor would only imply resetting the EMs to the strength required for that to happen.
