The constraint prevents individual loads from decreasing their loading level during restoration, i.e. when some power is restored, it can't be diverted to another load in the next time period.
++ this reduces degeneracy in the problem when all loads are treated equally, preventing power from being randomly shunted around to loads that have some shedding
-- This may reduce the total load delivery because reducing load to one node might remove some congestion that can allow higher load delivery elsewhere in the network
