Well, if you were to read shimano/sram instructions regarding chain length for cassette above 30T, you will find that once set properly, the derailleur cage goes over the cam point (and cam over) when on the largest cassette cog.
So when set properly, the lower point of the pulley is not on the largest cog (gear 1) but often on gear 3. and it is like that on my 5 bikes.
And it was demonstrated it in other posts:
