In the updated documentation for display filters, I say when talking about slices: 


Lengths can be negative too, in which case they mean the same as a negative
end offset. Thus, the following are equivalent:

    frame[-4:2]  == 0.1
    frame[-4--3] == 0.1
    frame[-4:-3] == 0.1


Are negative slice lengths useful?  I would suggest not.
