If you are in growth mode, say 20% growth or more -- and you are hiring quickly, your probably gonna have new dynamics form that change the shape of the team (Every hire changes the culture). Some folks may no longer be the right folks. (Could even be a new hire -- I had someone who I had high hopes for leave in 9 months because they weren't able to mesh.) Businesses are people but business is cogs. (In both senses of the word) To be a manager in a large org, you need to constantly be refocusing the team on the goal. Drift happens. When you have 100 brains, you get 100 ideas. This "rule of thumb" reason is to make sure leaders are not languishing. It's very easy to see the people, and lose sight of the business goal. Are all 100 people aligned and driving towards the goal? (If so, amazing and you should fight to keep all of them.)
