I attempted to change the side of the belt a inserter would place onto, while placed horizontally, facing a parallel moving belt. Instead of switching sides, the whole inserter rotated 180 degrees.

I checked to see if vertical inserters work properly and they do.
I repeated this 100% using four inserter types, also with each different tier belt.

This is not a bug. Inserters can not be told to drop on far/near lanes. Only when the drop position is ambiguous can you set left/right drop positions.
