But as far as not doing too poorly, how sure will you be that you're not in or close to that 10%? For a lot of people who aren't completely assured of themselves, this is a constant source of anxiety. Couple that with the leverage your manager has to casually place you in that bucket twice a year if you haven't done enough groveling, and this is where a lot of the toxicity at Amazon corporate comes from. People don't want to help each other because they have to look out for themselves.
Over time I saw three kinds of people thrive in that environment:
1) highly competent, productive people who managed the culture and workload with ease.
2) people who have Amazon as part of their identity and will sacrifice their well-being or personal life to meet the bar
3) typical corporate sociopaths that are non value-add
In my opinion they are growing bucket (3) the fastest.
They also seem to be about to change this [1].

So yes, if you are not promoted, you don't get to stay - you are actually fired.
They have modified this for some positions like flight instructors who they want to keep. But in general it's up or out in military - that means fired before you get your pension.
Wasn't that a Microsoft invention?
It's been around a long time.
Several companies in Silicon Valley also used stack ranking, for example.

But I actually think it is terrible. It pits co-workers against each other and makes taking credit for an accomplishment more important than doing what's best for the organization.
Though the culling should only apply to those at the bottom, not the top.
The culling is necessary to maintain top performance.
You're basically put in a position where you don't want to do too poorly, as you're guaranteed to get fired, but you also don't want to do too well, because then you may hit your ceiling too early, end up being "overpaid", then underperform and be set up for the cull.
I've seen both, and the yearly ritual of managers coming in and tapping people on the shoulder, them walking out to never be seen again ... I hated that.
