The three clones were almost identical, each able to use their powers.
When Jin's clone appeared, he was the most worried.
He didn't know how he would kill himself, and on top of that, the Chaos Creatures attracts to him when he use his powers, making it even more dangerous if the spiders approached them from the tunnels.
"Damn it, this is a mess," Jin muttered, preparing to face himself.
Then Jin's clone lunged at him, aiming a punch to his face, but Jin dodged it and countered with a punch of his own.
Then the clone kept swinging at Jin in embarrassing punches.
"Huh? Why isn't that clone using Blood?" Jin dodged an oncoming kick.
Jin and his clone exchanged several punches, leading Jin to realize something—that the clone couldn't use his powers for some reason which led him to several conclusions.
First, his power was truly unique, so much so that no clone could use it.
Second, he could use this to his advantage by switching with another person during a fight.
