By my reading I think you have it backwards. Here is the relevant text:
L Set to 1 if the prefix is locally assigned.
Set to 0 may be defined in the future. See
Section 3.2 for additional information.
Today, so far as I know, there is no defined allocation plan or system
for one to set that bit to 0.
