I think the interesting thing about this release was mostly that it was released, not necessarily that the information is not obtainable elsewhere.

But I dug up the diagram you mentioned just because I was curious.

Seems pretty different from the image in the linked post.

Yes, that's the schematic. To me the two look essentially identical save for topology and some imagined details.

I don't believe either of them are actually representative of a function warhead; see for instance https://images.app.goo.gl/aEBGKmAb8NsoAWe87, which suggests that in a real design the primary and secondary are inverted compared to the image shown in the blog post.
