Naively, yes. But as Dan pointed out, if a key K only exists in the minor partition (primary and backups), then just wiping the minor partition nodes will result in data loss.
A more sophisticated algorithm would just wipe keys in the minor partition that also exist in the major partition.
An *even* more sophisticated algorithm would only wipe keys in the minor partition that also exist in the major partition, that have changed since the partition occurred. Hence the vector clocks.
