Absolutely. The arrow is a dynamic, nearly independed system while it's in fight. The arrow is litteraly being animated over time. I consider the 'system' that describes the arrow to be in a 'same' state at N intervals. Like snapshots on film, these 'arrows' literally occupy two seperate locations in space. Are they two arrows? Depends on how you look at it - and when you do so.
