Faster than light
What that statement means is...
A person on earth left at speeds faster than light and arrived at Alpha Centuri - nearest star to our solar system, 3 days later. If he stayed there for 1.3 years with a telescope powerful enough to view the earth, he could watch himself leave.

No, there isn't actually two of the same person, all you're seeing is the image, which is simply rays of light, not the actual person. It's like seeing a picture of a person and thinking the picture is the real person.
Werd, basically, since when you were at point A the light reflects off of you, as soon as instantaneous travel occurs, you are travelling faster than the speed of light, so when you get to point B, the light being reflected that bounced off of you in point A hasn't gotten to point B yet
