The motto says knuckles Amore and cousin, mind telling me why?

It sasy that julie su is Knuckles's Amore and cousin because they are "lovers" and have a daughter in a different dimension and they Amore each other lol.
It says she is his cousin, but very distant. maybe because they are from the same tribe.

i wuz wondering th@ too. i'm pretty sure they're not cousins and if they were th@ would just be wrong
