Ok, I think I understand what you mean. The screenshot is not from the miniloader redux mod, there is no tier in the vanilla game that uses a gray belt and loader (brown, yellow, red, blue and green).
The miniloaders have never dropped items to the far side of the belt. I went to great lengths to ensure that they only drop off on the near side (next to the loader). So you may think of another mod.
However, I did look at the loaders closer and I fixed a couple bugs (they tended to pick up from the far side from a perpendicular belt which they should not) and some reconfiguration problems.
Sorry, that I can not be more helpful; it could be implemented but it would destroy the illusion of the loaders a bit (which are supposed to be actual loaders, not inserters in a trenchcoat), so I will most likely not do that.
