It's because Kokoro is such an old song, and was created years before Gakupo's release. As a result, most of the hype for Kokoro occured before the song "Goodbye, Thank You" was written. Another reason is because the official sequel was never released on Travolta's NND account. So basically, at the time the song came out, the only other male Vocaloid was the still relatively-unknown KAITO. The release of Kokoro Kiseki bolstered fans to view Len as the scientist despite not being by the same author. Most people don't realize he isn't the scientist or that there's another song.

Basically, it's because the answer song came out so long after the original that people made up popular theories and never realized there was something to counteract them, plus most people not knowing Kokoro Kiseki is a fan sequel.
