The first possibility is unlikely, while regarding the second possibility, when Zhou Tian discovered that the Space God King he was attacking was only a clone, it meant that the Space God King had already left his surveillance range. Given the Space God King's abilities, once he's given that bit of time, if he truly wants to escape, getting out of that Treasure Space has become much less difficult.
This isn't a question of difficulty; even if unintentionally, in such a circumstance at the time, allowing the Space God King free action makes it seem as if Zhou Tian and the Undead Divine King had given up their intention to kill the opponent. With the Space God King's tactics, in that situation, the possibility of Zhou Tian and the Undead Divine King being able to block the opponent was already slim.
