The Steel fight could have hinted that he only temporarily copies powers. The steelplate on his chest went back into his body after he defeated Steel.
Well going by DDs looks you could say there're more DDs, Henshaws DD looks heavily different from Superboys.
But it's most likely just an artist thing.

Just seems that if it is the same version of DD, he would be using some of his newly acquired powers against the various Supermen he battles -- but he never does.The issues usually start off with DD already fighting a version of Superman, then copying their powerset, then owning them, then leaving with them.
What he didn't think he needed them? Connor said he was using tactics. What if he's sentient and in control of what he evolves? fear
