Once you move one foot ahead, you are no longer standing in your previous physical position. Basically, there should not be two -or subsequently, infinite- YOUs in the spatial dimensions. If the same applies to Time as well, then it would mean once our world as a whole has passed a certain point in time, NOTHING of our world remains to be seen at that point. Not ourselves, not the buildings, not the trees. What's left there is either a/ nothing, or b/ something else completely outside of our spatial dimensions, not a duplicated version of it.
To have multiple correlative versions of one same thing is kind of... mind-boggling.
I think 'afterimages' would be correlative to footprints. Each 'afterimage' would be proof that you were there and time travel would simply be moving back to that print.
Time travel as a whole is just fantasy, though. It's a romanticized notion that we should be able to change the things that have gone wrong in the past but all things are relative and what's wrong for me may have been right for you, so the ability to change that would require the power to strip away free-will itself, which is (hopefully!) beyond anything humans can ever reach.
