I think people are getting the wrong impression when they think that a single impression will break you out of any single status effect. In my mind I picture these inspirations having a magnitude to them much like the powers themselves.
Geko said all players have a normal status magnitude of -1. As soon as that number hits 1 or higher, the effect kicks in. For example, let's say you're fighting a Rikti Mentalist whose holds are magnitude 3 (I'm not sure of the exact numbers). The hold lands and you're now at magnitude 2; and held. Pop the inspirations and you're status drops back down to -1, freeing you from the hold. However, that means multiple holds can't be broken out of so easily. Say two Mentalists each land their hold bumping your status to 5. A single magnitude 3 inspiration only drops you down to 2, keeping you held. Anyway, that's how I imagine it might work.
P.S. - I hope I made sense.
