If it makes sense to you or not is irrelevant, because no explanation was offered by Kishimoto in the first place, so anything goes. If they say Sakura's grandmother is a cow, we list it as true, unless Kishimoto comes out and says that Sakura's grandma isn't a cow.

And that's the problem: Anything goes and we have to document anything, even the most senseless shit (manga or anime, doesn't matter). I mean, you can see the uproar in this wiki each time something new is released? May it be Boruto's Byakugan, Hagoromo's Byakugan or whatever. Is it too much to ask for consistency? The anime is the last possibility to fix Kishimoto's mistakes, but they just constantly make it worse.

But as Jou said, if you're out for some easy entertainment without looking for sense and logic, the filler are okay-ish.
