Simply being part of the same continuity doesn't mean the two Sonics are the same character. Furthermore, Sonic isn't heavily inconsistent with this, unlike Mario and Paper Mario. There's plenty saying that PM and Mario are the same guy, but there's nothing to contradict Mania Sonic being a different character from Classic Sonic. And considering they look similar, it's understandable how Sonic could mistake him for the last Sonic he seen.

I do feel like Mania Sonic is probably the same as Classic Sonic, but there's literally no other way to explain the "dimensions" statement by Tails and Eggman. Classic Sonic isn't from a different dimension; perhaps Mania Sonic is though, like I said.
