Can someone please help me.. I'm confused.

INFORMATION FROM THE VISUAL NOVEL:

Sending the first d mail triggered the Time Machine of Suzuha to crash, thus the seminar got canceled, *thus Kurisu lives, thus the present world line that we are waching.

According to Suzuha, the root cause of the Alpha world line where SERN rules the future and Mayuri has to die was "The act of SERN tracing Okabe's sent d mails including the first one", (Not the the act of the d mails being sent).

And that in order to go to a Beta world line to save Mayuri and prevent SERN from ruling the future, Okabe must just "delete the records of his d mails in SERN's database" using the IBN500, so the future would adjust into a beta world line where SERN did not trace the d mails.

However, the IBN500 is currently lost. So according Kurisu's plan, they had to delete recent d mails in order to go back to the time when it was still with them, to be able to delete the data in SERN's database.

Now following the plan, by canceling some recent d mails, they got back to the time when the IBN500 was still present. Take note that at this moment Kurisu is alive because the first d mail has not been undone. They DO NOT need not to undo the first d mail because they already have the IBN500 at present to delete the records in SERN's database.

NOW, THE WAY I UNDERSTAND IT FROM THIS POINT (Start of ep 22):

Following their plan, from this point when Kurisu is alive, Mayuri is alive but is to die soon, and the future will be ruled by SERN, and they now have the IBN500; They can create a SPLIT in world lines to create a Beta world line from this point where SERN will not rule the future and Mayuri will live, and Kurisu still lives; by drastically changing the past of Alpha world line at this point, BY deleting SERN's records of their d mails (the root cause of SERN ruling the future and Mayuri's death).

QUESTION:

Why did they need to "UNDO" the first d mail? (And so he went back to the world line when karisu died), and if he splits the world line from that point to create a Beta world line, it will be a world where Kurisu is dead. if he could just Split the world lines when he just got back from the future and finds IBN500, by deleting SERN's records at that point when Kurisu and Mayuri is still alive beside him.
