My E24 had the same sort of catch spot above the spoiler when the drain holes were clogged. It was 24 years old and hadnt corroded there yet.
My Scirocco had the rear spoiler in the middle of the rear glass which would catch water in again the same place, that was 20 years old and .. no corrosion there either.
It seems its a coupe design, but to say it was a fault is definitely too early to say.
