Since kindle PW1 also has readyToSuspend, I suppose it goes to standby mode instead of full sleep.
Apparently this is not the case for kindle PW2
I very much doubt it. Much rather some other piece of software is deferring the suspend. If you keep looging everything, maybe this becomes more obvious.

Code:
#!/bin/sh

while [ 1 -eq 1 ]; do
    echo "waiting for event ...
    lipc-wait-event com.lab126.powerd * >> /tmp/powerd.log
    echo at `date`. >> /tmp/powerd.log
done
Keep this running in the background (I did not test this script, so maybe try it manually once), disconnect the USB cable, power-off the PW1 and wait 5 minutes. Then connect again and check the log file.
