Yeah he sensed it while unconscious and from across the map, there's your sleeping CoO feat
Everything you've shown is very, very basic stuff for upper-YC/low-top tier fighter range
I mean reacting to a point-blank explosion or shigan? Wow super top tier lol
Lets talk about Explosion.
Here is the only fundamental difference between Future Sight and Normal CoO. With Normal CoO, its like Spider Sense, you can only predict the Attack is coming but you can't see it so perhaps you can dodge it, or get out the way of the attack.
Future Sight shows you an actual picture, or an image of an attack, how ever many seconds into Future you can SEE. Operating word being SEE.
Otherwise both Future Sight and CoO are the same thing.
King's Explosion said to have killed Zoro had he not made either a 360 Barrier or Coated himself in Full Body Haki, that's especial prep-work to deal with special attack.
Zoro took Zero damage from that attack, meaning Zoro coated himself before explosion was even launched. So Zoro must have seen the explosion to know it is indeed explosion as Zoro hasn't dealt with King before. And he didn't exactly jump a whole mountain range away. If it was normal CoO prediction, he wouldn't know to make special preparations.
That's why it is a Future Sight like feat. Maybe Zoro has it idk.
