Thanks for your responses.
My task is to organize image loading sequence in two img objects in DOM, then to play tweens. The problem is that at the time of creating tween I don't know on which image object it will be playing. I came up with a solution of creating same tween for each img object and playing whichever is appropriate at the time of playback. At first glance duplicate objects don't look good, but that duplication will not even consume noticeable memory. So this solution is good.
