Quick Item Mapping=0, what does this do?

From (the original) BG2's Power Users.txt :

Found in [Game Options]:

Quick Item Mapping=1

When activated, only the abilities from items in the quick 
item slot can be mapped.  When deactivated, any ability 
from any item can be mapped into the quick item slot.

This sounds to me as if deactivating this option should allow you to place an item ability, e.g., from a weapon or ring, in one of the 3 quick item slots (which sounds as if it could be useful).
But the only behavioral difference I find with Quick Item Mapping set to 0 is that the items from the 3 quick item slots are duplicated in the use item (F8) menu (which feels not useful at all).

Is this option implemented correctly in BG2?
What's the intended use?

I've never heard/used that feature and I don't really understand what you expect from it so I can't really help you and I'd be surprised if I was the only one in this position.
