Um, maybe there's something I'm missing, but the way I read them, the two assumptions don't really work together. Read no. 2 first:
Okay, so I encounter a level 10 fighter, he must be CR 10. Fair enough. Now go back to the first principle:
So this level 10 fighter is a challenge for 4-5 level 10 characters? Okay, my party is five level 10 fighters . . . and this single level 10 fighter NPC ought to challenge them? Does that not seem ridiculous to anyone else?
Don't get me wrong, I was very interested when I read the rest of that post, and I'll probably look at the whole document more thoroughly. I just couldn't get my mind past those two principles, as written.

eg. CR 15 suggests the opponent would be a moderate challenge for a party of four (or five) 15th-level characters.
