Please don't lie. Apart from the fact that you've mentioned it once (which will have been recorded), so long as you don't touch them now, then you don't have a problem. Although I can't remember details, I do remember that they changed the question and the (automatic) reaction some years ago, to allow for such people as yourself. Take your advice from people who are up to date. Even going back to your CIO and asking them EXACTLY what the policy is, may put your mind at rest. After all, CIOs take their guidance from OASC and receive regular policy updates.
Otherwise good luck.
Unmissable.
