The parent post explicitly took the client bandwidth into account, that's why it was 100 instead of 10.

But your point about 10 vs 9 still stands. Still, 81, and if you bucket into 3 tiers, that's still 27. Which at least scales linearly instead of quadratically.

Exactly. It scales linearly, not quadratically. I forgot to mention that since clients do the "original" encoding, the server actually does less work (regarding resolution tiers).
