• bro, do u even b-screw?

    What I'm saying is that the upper pulley will move closer to the biggest cog once you shift to the small chainring, and it's already pretty close in Ed's picture.

    But Ed says it works, so I guess not a problem.

    You’re correct in general as rear derailleur do that.

    However the jockey wheel did not move at all in the latest Shimano derailleur.

    Please ignore the mere mortal helping me demonstrate this in this gif;

    That explains it. Case closed! Thanks for the explanation.
