No, it's incorrect that signs "point to each other."
There are multiple ways to get to various lines' platforms. This is not signs pointing to each other, this is signs in different places pointing to the same destination.
I live in Tokyo and while I do not go through Shinjuku often as I mostly live and work on the east side, I have no issue using the signs to find the platforms and exits I am looking for.
If you pay attention to what the signs have written on them, they will take you where you are trying to go.
Yes they are. Every time I visit Tokyo I try to avoid Shinjuku because it is extremely confusing and I always get lost.
Signs are mostly useful for people who are new to a place, if you need a significant amount of time to familiarize yourself then they are useless.

TIL 21 years is not enough time to notice confusing signs.
Two signs pointing at each other (I've seen way more of this but here is one example): https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSe-8IR...
In addition to signs pointing to each other, you also see several signs at once pointing to the same thing in opposite directions: https://skyticket.jp/guide/wp-content/uploads/pixta_46188735...
Or signs pointing the same direction for both East and West exits: https://basyauma.com/wp-content/uploads/2020/01/IMG_5141-2-1...

Same thing at Ikebukuro: https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....
There are many, many more examples of this.
All of those signs legitimately point towards the destinations on them. I don't understand what your argument is.
