Using something similar to a benzene ring with spokes sticking out of it is absolutely a reasonable choice for depicting sodium hexametaphosphate in a schematic. This is actually a pretty common choice in scientific literature regarding this molecule.

If you look at it more carefully, it isn't really a benzene ring, though. It's got multiple layers to it.

And the neural net crossover is just wrong. Really, really wrong.

This is nominally educational content. Any way in which it is wrong is something that people can and will pick up on and form incorrect assumptions about which they will carry forward. It's not enough that it is vaguely sort of, if we're generous, isn't entirely wrong. That's not the bar for human work either.
