From what people have said the 10 seconds only starts after you actually reach your ball. But if you were there at your ball sizing up your shot for more than 10 seconds and then it started to roll down the slope, then yes, presumably you could quickly hit it while it's moving. Otherwise it would be inconsistent with what we've discussed so far.I think, for sure, they waited far too long but obviously they could see the ball moving. However the rules are the rules and the penalty should be applied.
Just out of interest, if the ball is at 'deemed' at rest after 10 seconds, and your approach has stopped at the top of a green slope and stays there for over a minute, but whilst you're walking to it putter in hand and it starts rolling, I assume you cannot hit it whilst it's moving (even though it's deemed to be at rest!) and you have to play it from where it stops?
