Out of interest, why does Google use the term "paused" rather than "off"?

It makes me suspect that they are still saving it, but just hiding the fact that they are doing so from me. Or am I just paranoid?

Update:

The end of the article outlines this a bit better:

  Turning voice Activity off doesn’t stop Google storing
  your recordings, but it means they get kept with an 
  anonymous identifier, and can’t be easily linked back to 
  your account. If you want to stop Google recording your 
  voice at all, well, there’s only one solution: stop 
  talking to it.
