Thank you for whatever this is~

My answer is that it really depends on the Yoshi, and/or the person that owns the character, and the lore they want to go with.

That's why there's a follow-up song from the same artist called "The Devil Went Back Down to Georgia.", you see, Johnny made the mistake of challenging the devil to come back at the end, and lost his soul later for it when he was older and more feeble.
