Shadowcloak of Nocturnal

Hey guys.
So, this greater power: Shadowcloak of Nocturnal...

Spoiler:

Obtained by finishing thieves guild quest line

SHADOWCLOAK OF NOCTURNAL
For 120 seconds you automatically become invisible while sneaking.

I dont get it, I have used it a couple times already and they have had mixed results.
Some times, the power would last forever or until I activated something (like a normal invisibility effect)

I was under the impression that the power allowed a controllable invisibility effect of 120 seconds, toggle-able at will to preserve it when un-needed... this doesn't appear to be the case though as I just spent about 5 minutes mucking about with it...
Does anyone know the REAL effects of this? The REAL duration?
It would be much appreciated. Thanks.

When I chose it I assumed it would be just like the invisibility spell but will break as soon as you touch something normal. That seems to be the case with me as it only activates once with me when I cast it and go into sneak multiple times during the 24-hour in-game day.

It only works during sneak mode...doing anything, including standing up, cancels it. However, going back into sneak mode while the effect is still active will turn you invisible again...

I've done some more experimenting. This actually allows an infinite invisibility so long as you touch nothing while sneaking! You can stand up, open a door, then crouch again to re-activate it even after the duration of the effect! But the " going back into sneak mode while the effect is still active will turn you invisible again" won't work.

I must have kept stealing items while sneaking after using the affect as I assumed it only work the once in-game, the description needs to be more clear i think.

I changed it on the Skyrim:Powers article, I don't think I'm allowed to do that though, because it's supposed to be the official description.
