For (1), think about this concrete toy example: say the first thing you do is raising your right hand. The mirror clone rises his left hand. Then say you have an instinctive reaction behaving in this way:
if I see a person raising his right hand, I repeat that movement.
if I see a person raising his left hand, I do nothing.
So the next thing you do is nothing, while the next thing the mirror clone does is raising his right hand, which differentiates you from the clone.
HOWEVER, I now realize I was wrong: the mirror clone’s notion of left-right is mirrored as well.
As a human, you react to what other humans do around you. Your reaction algorithms may not allow two copies of you to mirror each other.
The clone is not mirrored, so you are not in front of a mirror you, but a rotated you.
I don’t think (1) works like that. Because both our reaction algorithms would yield the same actions?
Regarding (2): I suppose for this to work, the clone should be mirrored as well? I guess the advanced aliens can do that.
Ok, let’s say the clone is mirrored.
