I’m struggling to understand the rationale behind placing a supply vent directly next to a return vent (even if it is a jumper duct). Is there a functional purpose for this arrangement, or is it indicative of poor design? It seems counterproductive to blow out conditioned air only to have it immediately drawn back into the furnace. There’s a supply vent at floor level in the room, so this wall vent appears to be for seasonal airflow, but I still don’t understand its purpose. Can someone please enlighten me?
Don’t try to understand it! It’s wrong.
Duct design is complicated and not part of your job. Don’t lose sleep trying to understand.
You need to know what type of ducts these are and their intended purpose. You need to know this before you attempt to say anything about it.
Focus on that big crack at the wall register thich is wrong. If it is a supply, it is leaking into the wall. That is something you can write up.

I’m not saying that you are incorrect in saying that it is the supply and return.
Be careful with always assuming that a return air grille means that it is a return. When I was in the HVAC world, we would offer a fake return air grille instead of drywall repair if we needed access to finished areas. This could be for running new control wiring, venting, or line set. Other trades do this as well. Most homeowners choose this over spending a few hundred dollars in drywall repair and repainting.
They can also be used in areas where pipes are prone to freezing.

What does that mean?
It’s either part of the ductwork (return, supply, something else) or it isn’t.
