The character at the ending was the inspiration for Lori yes, but Lori was still created as a new character. Read this quotation, "That yellow bunny seemed good (and I love female playable characters), but she was too goofy looking."

The thing about Noogy's statement is that if the yellow bunny girl at the end of the cinematic and the new revamped Lori was the one and same character, then you'd have to explain a plot hole where the character literally changed design.

Instead, there was most likely intended no direct connection between the two and Lori would just bear resemblance to the previous girl.
