To me it reads that way due to the way you presented the information visually.
 
You got a section boxed in dividers after the explanation of how to do attacks and you capitalize the three different tiers of wounding, which makes it look like this is how the health work in the game and on top of that it makes no connections to your HP system and it's long which implies importance . So looking at that it seems like we're using some sort of "dramatic" wound rules where you got these tiers of wounding which escalate and if you get the highest wound type you're good as dead.
 
Then you got the section involving HP and it's separate from the wound thing and very brief so it looks like an entirely disparate health system that escaped editing or worse some unexplained fiddly bit in the health rules.
 
Also you should explain what exactly do these three wounds tiers do mechanically.
