I fear that's the same feature, but is entered into the feature database using different names for the different OS architectures, hence it shows up differently. Both support the "capability vrf-lite" knobs, so both can be used in a "real" MPLS-VPN PE-CE setup as well as in a vrf-lite environment where the addtl. loop prevention logic is not required/counter-productive..
