What's the point/benefit of putting the disc mounts way out here behind the rear axle? And can anyone ID the frame?

Only on one side, and you can see the rack and fender mounts in their normal position just above the axle.

It will not interfere with rack and fender when attached like this. The small-ish rear triange might also mean the brake may not fit inside.
That makes sense. Though it makes me wonder why it's not a common design.
Usually the brake caliper is placed inside the rear triangle to avoid interference with the rack, but the brake may not fit if the triangle is smaller or has tight angles; this bike looks like smaller than 50cm, so that could be part of it.
Taking another look, this design could also reduce the cost of manufacturing since the drop out and brake holder is all once piece. If the brake holder were on the seat stay or chain stay, it would require welding an additional piece.
That's only on newer (I mean, post-2015) bikes. Most older bikes have the mount right on top of the dropout, which interferes with most rack mounts.
None of my bikes are newer than 2015 and they're mixed. Brake above the dropout will accomodate a larger rotor, whereas my bikes with brake inside the triangle are limited to 160mm.
