It is a redundant setting once the mains are set to small. The LFE+Main setting is only active for main speakers when set to large. Once they get set to small the LFE channel is still processed in the same manner as LFE+main w/spk large, all frequencies below the crossover and LFE is sent to the subwoofer and not to the mains.
I guess because it still works in the same manner for either speaker size Denon didn't think it needed to be removed as a possibility.
