Weird string arrangement on the nut - why?

Basically a worse version of accidentally grabbing your B string when starting a restring on the 1st string,,,,,and then not realizing it until you start coming up to pitch/tension.

I would bet that the D string broke and isn't long enough to reach the correct tuner so he swapped the A and D.

That's the only "valid" reason I'm thinking that wouldn't mean the guitar had some super weird problem that means it should be passed up on

I bet the owner is a moron.

Based on the number of winds around the post, I’m gonna say nope. The D string would reach just fine.
