It adds drama. Hazel fell in love with Sammy, but then died and came back. She then got a boyfriend, but instantly found out from a video scroll that there was this kid that looked and acted a lot like the boy she still had lingering feelings for and was her first love to boot. Then we find out that Sammy made a request to Leo to be his "stunt-double," possibly placing some kind of blessing on Leo that resulting in Leo acting and looking like Sammy.
