Can I log into Netflix on the web on mobile all accesses are occupied WITHOUT having to pay extra?

Is that possible?

Netflix is just that if (as an example) you have the family subscription 4 people can watch a series or a movie at the same time. Now, if a 5th person would join (and start a movie or series), there would either be a notification that 4 people are already watching something, or one of the 4 people would be z. From the movie she looks "thrown out" and the 5th person would then have one of these 4 places Free. (Actually, I have not tested this yet but one of them should come in)

So in the end, you do not have to pay anything extra.

Okay Thanks now I know
