Why is the cell not 4n when dna replicated?

I know that it's common nomenclature that when a 2n cell replicates its DNA it remains 2n, but is there any reason they named it that way?

It doesn't make much sense since from a practical standpoint it has 4n chromosomes.
Also, during a brief moment in anaphase, the cell does actually have 4n chromosomes, if you think about it.

It all seems pretty stupid to me...

I think it's because these are not 4 differnt chromosomes, but always 2 make an identical pair, which even does not go away, but is bound together

Cis or trans? That's what matters.
