It's a Hartford Loop!

Ok, just a little Oregon humor, there. I really have no idea.

Guess: The installer thought that he needed some more friction on this duct run in order to balance his duct calcs, so he added length and a few bends.

Or they could have just added a damper.

I have no idea either. Mad at the boss and using more material then they should?

My guess is they overshot the vent hole with that long run, and just too lazy to take it out and cut it down.

Or the homeowner wanted to relocate it because it was under their couch.

I call laziness.

They didn't have the right parts on the truck at the time and they didn't want to cut any sheet metal.

You can take one of those 90s and twist it to be two 45s and therefore a direct hookup.

Retard is one word that comes to mind.
