Whatever the usage is, I just hope that 4349 won't end up being just an answer to another bullshit reset puzzle; I'd be super unimpressed haha, even more so than just being plain meaningless.
But I've been thinking about that Kaori scene due to a different reason, it's how she glitched out.
From the description of
There Is Nothing, the "digitized glitchiness" might be the signature influence from the 2nd god, and IIRC the only other person that ever glitched like that before this Kaori scene was exclusively Ami; the rest glitched examples are all acid dreams with mashed up jpeg (not to mention in other scenes it might be Sensei who was glitching out, whlie in this case Kaori and Ami were clearly the ones under divine intervention)
If this can indicate that the Sekai-possessed Kaori is under 2nd god's influence due to the unique visual alterations, then it will strengthen the idea of 2nd god
is Sekai. It will also explain why Ami is considered by the 2nd god
the right person to control; or at least it makes more sense compared to another strong candidate Mr. Tojo (why and how would he consider Ami as the right person anyway lol)
Yet again there is no guarantee that these shock value things are meant to interpret this way, and there are other things said about the 2nd god in
There Is Nothing remained seemingly unrelated to Sekai, god of science itself, being calm and does not mind or act on things, the pronoun /he/, etc. So yea, just throwing thoughts in the air.
