But that's the problem: we saw this very device perform its second-ever cloaking of a starship, and there was no indication of an uninterruptable countdown.
Who turned the device on and why remains an open question. Might be the ship was already cloaked when Pressman made his escape, of course - due to the firefight, he never got a chance to turn it off. The mutineers in turn flipped the switch immediately after gaining control of the device, which was a stupid mistake because they happened to be inside rock at the time - but it's probably understandable that they wouldn't have stopped to coordinate with Bridge at that point, especially if Bridge was still in Pressman's hands when the mutineer group set out to storm Engineering.
