I'm used to the way Sparky thinks so none of this is shocking to me. I think he knows Tails and Cream aren't literally the same characters, he is just completely unable to think without his archetypes for some reason

Anyways it would be cool if they used Cream more. Her stories aren't as good as Tails' and she doesn't have relationships that are well developed and explored like Sonic and Tails. Tails is one of the most interesting characters in the series in all aspects, Cream really does not have as much going on
