> I really do not understand how Luka sending the video D-Mail changes anything at all.

This does changes something as we could prove that two worldlines are active if it weren't the case. Okabe (from 2025) (if Luka hadn't send the nostalgia drive) sends it and Okabe (from 2010) receives it and also it takes some time for Daru to build a time machine. The point of our discussion was to prove if multiple worldlines can be active at the same time or not. This point was very crucial for me as I haven't read S;G 0.
