What happens if you watch Netflix on 5 devices?

We have the premium subscription and therefore we can create 5 accounts, but we can only watch 4 at the same time, I've read. If 4 accounts are already looking and the 5th logs into his account, will someone be kicked out or the 5th just won't come in?

The 5 can't get in, the problem often runs in the family

Oh, so nobody gets kicked out in the middle of the movie?

Nope

So yes no one is thrown out
