Yeah I've ran into similar bugs with bins seemingly 'copying' themselves.
What is actually happening is the reference to the inventory of the bin is being copied, not the bin and the items themselves, that's why when you deleted one, it deleted all of them.
The strange thing in your example though is you were actually able to drop multiple instances, which I haven't ever been able to do myself.
Normally if I try to do anything with the bin after it is 'copied' I get an inventory request error.
I would recommend that if something like this happens again, immediately transfer the contents of the bugged bin into another regular bin, then delete the bug bin.

Off Topic !!!

BTW: if you re-log then this bug is gone - its a client side bug ... (at least it was one), the tip from preston is valid - do not mess around with bugged baskets - the best thing to do is to re-log, then everything should be back to normal. Deleting the basket is not a good idea in my opinion.
