Similarly, if, in need for divine inspiration, you look up to the heavens and see Stevo wildly gesticulating at you, you suddenly think "Ah, I'll try the chip over the top, thanks Stevo!" (regardless of where the full back - and all the other defenders for that matter appear to be - they are inconsequential to our Lord Stevo naturally...) - the intention is obviously to try and retain possession, so if the opposition team catch the ball, technically it's an uncompleted set, however when you kick the ball you know there's a chance you may not get it back, hence choosing to risk ending the set, hence making it a completed set. Obviously.
