itemReorder when the item is returned back to its initial position

Hello!
Regarding itemReorder, I have noticed that when you drag an item to another position without dropping it then you return it back to its initial position, the indexes object shows that it was moved 1 position ahead (or behind).

I would like to know whether it is a normal behavior or not. I think it would be better not to take action when the item is returned back to its initial position.
