No, it's thinking about balance so villains can't start making our life absolute hell. I think the above is a very good starting point, but I also think it's pretty limited in how far it'll get you. *

However what is especially good about it is that it's something you can build on and add too (all I was suggesting) and learning how to adjust our range vs different players is very important. I'd just say that as we start playing better players our natural starting point should move towards a more balanced form than this.

It's not like this range doesn't take into account balance at all, that's the only reason 3bet bluffing comes into it. Someone just starting playing could do the exact same analysis and just have a calling range and a 3bet value range, but what we should start to realise is that this is a exploitative adjustment to exploit population tendencies.

edit -

* I mean using this range as a starting point, not the idea behind what he's done.
