It means the same thing. It's just that he's not randomly pumping Sasuke full of cells but rather that he's delicately using them to fix him.

Zetsu have almost non-existent wood release, and they have his cells. Given that Kabuto had access to zetsu and Sakura had access to Zetsu, i think it's clear that Sasuke got some of those weaker cells (since they also don't murder you when you run out of chakra), as did Naruto for his prosthesis.

Neither needs the power upgrade, making a weak but controlled injection (IE zetsu material) a far superior option to "gives loads of power but fucks you over when you have no chakra" IE the Danzo option (or any of the other 24-ish Yamato candidates).
