Conflicting description on getSnapshotBeforeUpdate section on the React.Component page

Page: https://reactjs.org/docs/react-component.html
Section: getSnapshotBeforeUpdate

The description after the code block reads

In the above examples, it is important to read the scrollHeight property in getSnapshotBeforeUpdate because there may be delays between “render” phase lifecycles (like render) and “commit” phase lifecycles (like getSnapshotBeforeUpdate and componentDidUpdate).

It is indicating that we should be reading the scrollHeight property in getSnapshotBeforeUpdate due to the delays between the "render" phase lifecycles and "commit" phases lifecycles. But getSnapshotBeforeUpdate is indicated as one of the "commit" phases lifecycle. Is that correct?

閱讀 https://reactjs.org/docs/react-component.html 上 React.Component 頁面中的 getSnapshotBeforeUpdate 區段，包括程式碼區塊及其下方加上引號的說明。檢查該描述是否正確區分了 render 階段和 commit 階段的生命週期，然後更新相互衝突的措辭，讓生命週期時機清楚明確。
