I know this story, bodhisattva means a person who chose to live after attaining Bodhi for other people. It's said Bodhisattva was born probably because the person knows the entire story. Even Dr. B R Ambedkar/ Samrat Ashoka are termed as Bodhisattva, doesn't mean they were a rebirth too but simply because he attained a wisdom that is unbiased.
Logically speaking all Buddhas get same knowledge probably because there's only one truth, there's no need to be reborn and to go through all those trouble again. Thus they're different people. The texts were written (very later in time) just to guide other people.
