And I suspect you are right as long as current leaders wield the power. Periodical purges in all ranks of power and society are a time-tested feature of communist regimes. Without them the party cadres grow stale and lose their revolutional vigor. I can imagine it's a bit similar to how the free market works, with companies going bankrupt or taken over all the time, only there it's the changing conditions and the 'invisible hand of the market', while in communist dictatorships it's always intentional and directed (and way more brutal), because the rigid system does not self-regulate, at least not the way the leaders would like.
