Quick tethered jailbreak query

I am trying to help someone out with their jailbreak and their ATV2 is stuck booting with Apple logo on screen. Is this a sign that a tethered jailbroken ATV has been rebooted? Ie. is this what happens when you reboot a tethered jailbreak without going through seas0npass? Many thanks.

Yes - that is what one would expect.

Thank you
