What I meant was splitting from alpha to beta world line (change the future drastically/save the world from being rulled by SERN).

Anyway, thank you again Sir.

So I guess what I'm missing here is the fact that deleting the first d mail in SERN's database using the IBN5100 would "UNDO" the sending of the d mail in the past? Because if it did undo the d mail, I would understand why he jumped to a worldline where Kurisu's death is inevitable.

The thing is, the way I see it

DELETING the d mail in SERN's database at the time when Kurisu was still alive and they finally found IBN5100 would already save the rest of the world from SERN's future monopoly of Time Machines because they will never find out about Okabe's lab...

UNDOING the D mail is a different thing, where Kurisu has to die.

1) Am I right if I say that the anime also lacked explanation why IBN5100 was actually able to "UNDO in the past!" the d mails which it deleted? Because as far as I can remember it's just an old computer that can hack in SERN's database. And does not have a time machine attribute.

Or am I missing something?
